A new alternative notation, (Straub notation), is designed to make memorizing sequences of moves (algorithms) much easier for novices.

This notation uses consonants for faces (like Wolstenholme notation), but more variation option offer to turns (moves). The differences are the use of the vowels E and I (high vowels) for clockwise, of the vowels A or O (low vowels) for counterclockwise, finally of the vowel U for 180-degree turns (the shape of the vowel remind us the turn), so numerous word sequences can be formed.

Possibilities for vowel variation will serve the purpose of making the algorithms different form (although equal value) can be written, so these algorithms much easier to remember and memorize.

re-edit request

I'm bringing this issue to here (first edited 08:10, 15 April 2013‎ Spinningspark (talk | contribs)‎)- Rubik's cube solution walkthrough as external link (www.rubiksplace.com). This website was shown under external links as how to solve the rubik's cube walk-through. Along the way the guide had added "java applets" of the rubiks cube, so it got removed from the entry. it is against wiki links guidelines. Website had been modified so java applet shown only as an optional in a separate page for the comfort of all potential visitors (old browsers, no java add-ons)- no more java on the walk-though. Was advised to post it here to restore this edit. The guide is a very detailed solution which crafted according to many new cubers along the way. Maor. +1 for me. — Preceding unsigned comment added by Majorson (talk • contribs) 18:10, 18 January 2014 (UTC)

Semi-protected edit request on 24 December 2014

Hello sir, I am submitting an edit request. Getting straight to the point; here are the reasons:

1. I have come to tell you that this page has a lot of bias towards Panagiotis Verdes. The page is promoting his products by: Calling the 6x6x6 and 7x7x7 "V-Cube 6" and "V-Cube 7" respectively. Also, DaYan 3x3x3 cubes do not infringe any patents, if so, there is no evidence (and I know that it does not infringe the patents.) I feel this content should be removed.

2. Cube manufacturer ShengShou has been reported by cubers to have infringed Verdes' patents. Thus, their products are ilegal. There is plenty of evidence to prove that it makes pure knockoffs (while it remains the only company to have physically made the 8x8x8, 9x9x9 and 10x10x10.) It should not be promoted either.

3. 13x13x13 cubes are in production, their manufacturer MoYu has made their own patented designs. I feel that they must be mentioned.

Thanks, hope you give me permission. Jacobright23 (talk) 16:29, 24 December 2014 (UTC)

Not done: as you have not requested any specific changes.
If you want to suggest a change, please request this in the form "Please replace XXX with YYY" or "Please add ZZZ between PPP and QQQ".
Most importantly, you must cite reliable sources to back up your request, without which no information should be added to, or changed in, any article. - Arjayay (talk) 17:16, 24 December 2014 (UTC)

---

V-Cube is a trademark, and whether other similar puzzles infringe on patents or not, they do exist, and ought not be simply ignored. If mention of existence constitutes promotion, then every mention of Rubik's or V-Cubes should be removed as well.

The article mentions that Verdes' patent covers cubes up to 11x11, which means that unless Verdes' has filed another patent that is not mentioned, Moyu's 13x13 cannot be in violation of his patent.Small Brown Cow (talk) 19:44, 30 July 2015 (UTC)

other "versions"

This has recently been added: "All five platonic solid versions of Rubik's cube". Since out of the 5 platonic solids, only 1 is actually a cube, should we say something like "Permutation puzzles have been made in the shape of all five platonic solids." I realize that it's a common practice, because the rubik's cube is so much more popular than other permutation puzzles, puzzles that are not close to be cubic in shape are often advertized for sale in ebay as "rubik's cubes". What do you think? Dhrm77 (talk) 03:19, 18 January 2016 (UTC)

Cycle length for FRT?

If the Cube is turned Front Clockwise, then Right Clockwise and the Top Clockwise, how many turns does it take to get back to the solved cube?Naraht (talk) 17:41, 24 February 2015 (UTC)

Try it and count. I recall it took 15 minutes or so. - Richfife (talk) 18:13, 24 February 2015 (UTC)

80 cycles (240 turns) and much less than 15 minutes for me. After 16 cycles, 5 corners are moved around and the rest of the pieces are in place. PrimeHunter (talk) 18:23, 24 February 2015 (UTC)

Well, it feels like 15 minutes when you're 12 :). Thanks! - Richfife (talk) 18:35, 24 February 2015 (UTC)

If you start with a correct Cube, (otherwise it isnt possible to get a correct cube) I think you have to do FRU 40 times (120 turns). — Preceding unsigned comment added by 77.119.129.111 (talk) 16:12, 20 January 2016 (UTC)

There exists a fully functional 22x22x22 3D printed cube designed by an individual that goes by the online alias of corenpuzzle. This cube technically beats out the 17x17x17 record currently in place. Some videos have surfaced of a 28x28x28 cube however these have proven to be fake; the illusion created by re-stickering a 13x13x13 cube.

Definite article? ("Rubik's Cube" or "The Rubik's Cube")

The definite article ("the") is usually not used for possessives (it causes ambiguity). Should "Rubik's Cube" be considered a possessive or as if it was a single word? The article has it both ways, but for me at least leaving off the "the" feels stiff and formal. - Richfife (talk) 17:29, 8 April 2016 (UTC)

My advice is to trust your instincts. I agree, leaving off the "The" is kind of odd, so WP:BEBOLD and do it.

Hmmm... If you think the British to American drive-by's are bad, imagine the "Add missing 'the'" crowd. Probably best to leave it alone. - Richfife (talk) 00:04, 9 April 2016 (UTC)

Separate page for notation

Notation is a big topic of its own - I thus created a separate page to accommodate it, with the intention of expanding it over time.

However, my new page, of which I had spent hours, was promptly deleted and redirected back to the main Rubiks page.

I mean FFS is this why no one want to edit Wikipedia anymore? I have a lot to contribute but am about to give up and make my own website so that arseholes can't delete good material. — Preceding unsigned comment added by Noledj (talk • contribs) 11:18, 25 August 2016 (UTC)

I feel your pain. A number of people (I won't give names) seem to be a little too trigger-happy about reverting and deleting everything and anything... Your page hasn't been deleted yet. It was just blanked and redirected. You can still contest the deletion, or work on it in your sandbox. I believe there is probably enough material for this subject to be its own article. There are quite a few pages that are much smaller (namely 241 (number), 243 (number), 244 (number), 246 (number), 248 (number), 249 (number), etc..). Just in case it happens to be deleted in the near future, I saved it in my sandbox.

On the subject of various notations, I created my own notation here: "Rubik's cube notation". a number of years ago, and that I use throughout my website "Main puzzle page".. The reason being that I wanted every algorithm to be portable to every puzzle such as the 4x4x4, 5x5x5, 7x7x7, megaminx, gigaminx, teraminx, and even the 3x3x5 or any other variation. If you need to name with a different letter every single layer of a big permutation puzzle, pretty soon you run out of letters to use. Furthermore, you can't rotate the middle layer of a Megaminx for example, so different notation system is needed, in order to have a coherent system to describe moves on every permutation puzzle.

Numerical Notation

I recently made a change to include numerical values (2,3,5, etc.) as an addition to the English text (two, three, five, etc.). I did this because numerical notation (2,3,5, etc.) is compact and language-neutral. It is also programmer-friendly IMHO. However, my edit was retracted because it didn't "add new information". I think my edit gave a valid, alternative description. Not only valid, but without an English-language bias. I'm not sure why additional/accurate information is being deleted... is it a fear of Too Much Information (TMI)? Hydradix (talk) 11:29, 10 December 2016 (UTC)

Replaced References with Further reading

Hi, I got rid of the very random list of "references" on this page, since none of them seemed to be actually references for this article. Most of them are just 1981 cube craze books (a lot of Rubik's Cubes books were published in 1981-2). I replaced it with a "further reading" section containing various reference books. I'll stick the old "references" list here, in case I've made a mistake, or someone wants to see one of them returned to the page. I kept the Bizek book and the Dan Harris book in the new list, since they seemed, at least, to be newer or still relevant. Pasicles (talk) 00:02, 29 January 2017 (UTC)

Three books removed

I noticed some books got immediately removed with the edit summary: "Removing three, already being used as references". I was a little confused at this since a Further Reading section is "to help interested readers learn more about the article subject." It is true that one shouldn't try to duplicate the content of the References section, but WP:FURTHER says "unless the References section is too long for a reader to use as part of a general reading list."

Ah, that exception is something that has been added since I last looked. Thanks for pointing out to me that the guideline has changed. Feel free to put the items back if you think that it applies here. SpinningSpark 17:28, 30 January 2017 (UTC)

Ah I see, thanks for that. Well, I'll put one book back for now: the "Handbook of Cubic Math", since that still seems to be the main introductory text for Rubik's Cube mathematics. That other maths book in the section: "Mathematics of the Rubik's Cube Design", whatever it is about, seems to be a book that's very hard to find. Pasicles (talk) 19:46, 31 January 2017 (UTC)

Please change the statement on the top to the statement on the bottom. MoYu/YJ is one of the most popular and highly esteemed brands in the world.

Today, the patents have expired and many Chinese companies produce copies of, and in some cases improvements upon, the Rubik and V-Cube designs. The most popular are Bao Daqing's (包大庆) DaYan (大雁, literally Great Goose) company, which produces the GuHong (孤鸿, lit. Lone Swan Goose), ZhanChi (展翅, lit. Spreading Wings) and now PanShi (磐石, lit. Solid Rock) models, amongst others. They are often preferred over the originals by expert speed cubers because of their ease of movement.[16]

You will need to supply a reference from a reliable source to support that. - Richfife (talk) 18:34, 26 March 2016 (UTC)

I am not clear on what you want me to support. It is a fact that MoYu/YJ exists and has created these cubes. Here is their Facebook page to prove it. https://www.facebook.com/yjmoyu — Preceding unsigned comment added by TheGoldenParadox (talk • contribs)

Nobody is questioning their existence. The issue is that a reliable source, independent of the company making them, needs to be supplied that confirms the significance of these cubes. The company's own Facebook page is not sufficient. SpinningSpark 23:38, 27 March 2016 (UTC)

Oh. I do not know what is a reliable source though. Social media is not, but maybe Amazon is? Here is an Amazon page to prove it. Its description says clearly that MoYu is a very popular brand. http://www.amazon.com/D-FantiX-Aolong-Stickerless-Enhanced-Version/dp/B00Q094SIU

I hope you approve my request.TheGoldenParadox (talk) 13:45, 3 April 2016 (UTC) TheGoldenParadox (talk) 23:38, 2 April 2016 (UTC) Now, I'll just do it myself.(with the Amazon link, of course)TheGoldenParadox (talk) 13:57, 3 April 2016 (UTC)

I do not know if that particular brand is very popular or not, but if it is, it should be mentioned. Perhaps interviews of competing speed-cubers, if any journalist ever asked that type of question, or perhaps surveys done by the WCA, would be relevant. Dhrm77 (talk) 16:00, 3 April 2016 (UTC)

It is the responsibility of the person wishing to add the material to provide such sources. SpinningSpark 12:21, 6 April 2016 (UTC)

Dialect change

This page appears to be written in British English. Is there a reason for this choice? The extraordinarily high incidence of words like "colour" and "centre" makes BE a strange dialect to choose for this article as most readers will be confronted so frequently with an unfamiliar spelling.

What are the objections to changing the Dialect to American English? — Preceding unsigned comment added by 173.59.51.174 (talk) 16:06, 25 August 2015 (UTC)

You are asking for a system-wide change of policy for the English Wikipedia. The best place to make a case for it is at the Manual of Style talk page. - Richfife (talk) 16:15, 25 August 2015 (UTC)

I imagine that "color" and "center" look just as strange to people more used to British spelling. The rule that covers this is WP:ENGVAR. Short version: "If the article is about something American or British (or Irish or Canadian, etc.), use that variety of English. If it isn't, use whatever variety of English the first major contributor used." Since the R cube, which was invented by a Hungarian, isn't American or British (or Australian or Scottish), we keep the article the way it is. But yes, if you got consensus among contributors that this specific article is somehow better in American than British English, you'd be allowed to change it, but it looks six to one half a dozen to the other to me. Darkfrog24 (talk) 16:25, 25 August 2015 (UTC)

I'm against it. The two dialects are equally valid and unless the writer is intentionally trying to be obscure, there's no reason that the reader shouldn't educate themselves on the words and spelling being used. If you can round up support from native British speakers, then I'll be willing to revisit. - Richfife (talk) 16:38, 25 August 2015 (UTC)

"most readers will be confronted...with an unfamiliar spelling." Most readers are not American. There are 1.7 billion people on the Indian sub-continent (many times the population of the US) where English is used as a lingua franca and British spelling is commonly used. SpinningSpark 00:10, 5 September 2015 (UTC)

Maybe we should 'formalise' the issue with a 'use British English' template? 220 of ^Borg 04:07, 24 November 2015 (UTC)

On the actual article I meant. I note that there is a 'British English' template at the top of this talk page, and the issue has been mentioned before as long ago as 2006. [1] --220 of ^Borg 04:16, 24 November 2015 (UTC)

Visible templates should only be used on the article when there is a problem that needs fixing. This is not such a case. However, there are {{Use British English}} and {{Use British (Oxford) English}} (I haven't checked which one this article is) which are hidden templates to aid scripts that do spellchecking. SpinningSpark 14:42, 24 November 2015 (UTC)

They're the template/s I meant. 220 of ^Borg 09:44, 25 November 2015 (UTC)

I think that the English Wikipedia should use American English, and there should be a new Wikipedia that uses British English. However, this is just an opinion. I think the best thing to do is make a poll to actually ask users.TheGoldenParadox (talk) 22:28, 19 February 2017 (UTC)

Why limit ourselves to British and American English? Let's also have a Canadian, an Australian, a New Zealander, a South African... Wait... Let's have one for every State of the US, every time there is a subtle variations of language, new version... Dhrm77 (talk) 01:50, 3 April 2016 (UTC)

Because most states use American English, and most countries use British English.TheGoldenParadox (talk) 13:25, 3 April 2016 (UTC) But I also see your point. I agree with SpinningSpark that most readers aren't American.TheGoldenParadox (talk) 13:45, 3 April 2016 (UTC)

My sarcastic point (which wasn't aimed at you in particular) was that instead of fighting about if the dialect should be British, American or some other flavor, we should all (and I mean ALL people of the world) aim to adopt a common language such as Esperanto, that doesn't have the flaws and awkwardness of every other languages of the world that "evolved" naturally to the point that they need an awful amount of rules to justify their insane spelling, grammar or pronunciation. A language should be a tool to communicate, not a barrier to prevent people from communicating, and not an aim in itself (see grammar nazis). A language should be simple, logical, easy to learn, with no exceptions, so that we spend less time learning it and more time learning other more interesting things like solving rubik's cubes. Dhrm77 (talk) 15:55, 3 April 2016 (UTC)

That is asking for a system-wide policy change for the WORLD! Many people are struggling to learn just one language, and ~775,000,000 people around the world cannot read or write. Much of the world is focused on getting two meals a day, and you have to have different languages for different economies. Right now, it is going to be really hard to create a wroldwide language. And if it is, it is probably going to be Mandarin Chinese, as there are about 1 billion people that speak it as a primary language. TheGoldenParadox (talk) 14:38, 18 February 2017 (UTC)

"Relevance and application of mathematical group theory"

This article neglects to mention that the creation of a game or toy was a secondary consideration. Rubik's point was to physically embody principles of group theory in a manner that could be easily visualized. WilliamSommerwerck (talk) 21:45, 28 June 2017 (UTC)

Hello,

This paragraph under "Trademarks" is now incorrect:

Rubik's Brand Ltd. also holds the registered trademarks for the word Rubik and Rubik's and for the 2D and 3D visualisations of the puzzle. The trademarks have been upheld by a ruling of the General Court of the European Union on 25 November 2014 in a successful defence against a German toy manufacturer seeking to invalidate them. However, European toy manufacturers are allowed to create differently shaped puzzles that have a similar rotating or twisting functionality of component parts such as for example Skewb, Pyraminx or Impossiball.[43] On 10 November 2016, Rubik's Cube lost a ten-year battle over a key trademark issue. The European Union's highest court, the Court of Justice ruled that the puzzle's shape was not sufficient to grant it trademark protection.[44]

It should read:

On 10 November 2016, Rubik's Cube lost a ten-year battle over the black and white 3D grid trademark. The European Union's highest court, the Court of Justice set aside the ruling of the General Court of the European Union, the trademark invalidation case was sent back to the European Union Intellectual Property Office, which ruled that the puzzle function could be inferred from the trademark protection. Rubik’s are appealing this decision and there are other forms of intellectual property protection such as passing off, copyright, 3D colour trademarks and 2D figurative trademarks all protecting the visualisation of the Rubik's Cube and also numerous word trademarks in existence.

This paragraph is inaccurate:

"Non-human solving: The current non-human time record is for Sub1, a robot made by Adam Beer, an economist and industrial engineer. A YouTube video shows a 0.887 second solving time using an Arduino with the Kociemba algorithm."

It should be:

Non-human solving: The current non-human time record is for Sub1, a robot made by Albert Beer, an economist and industrial engineer. A YouTube video shows a 0.887 second solving time using a ShieldBuddy TC275 Arduino with the Kociemba algorithm.

Hi, The world record for the 3x3 single is inaccurate. The current official record for 3x3 is by Patrick Ponce and is 4.693 seconds. It was broken on 9/2/17 at Rally In The Valley 2017. Feliks Zemdegs currently holds the #2 position for 3x3 single, please update the chart for 3x3 world record single to this.

Thanks,

Optimal maximum number of moves to solve equation query

In the article it states that a cube of size n×n×n can be optimally solved in Θ(n² / log(n)), or in other words "as much as" the n-squared divided by log n.

When I do that relatively simple calculation for a 3×3x3 cube, I don't get the expected answer of 20 (which has apparently been worked out by Google and some very clever people, and considered optimal as there is supposedly a set of starting conditions that need at least 20 moves), but 18.836 - 3² being 9, and log(3) being 0.4771.

Obviously, 18.836 ≠ 20. So, have I done something glaringly wrong, or is there an error or bit of fudging in the formulae (or article)?

FWIW this makes the lowest bound of maximum predicted moves-to-solve for a 2×2×2 cube = 13.288, a 4×4×4 cube = 26.575, and a 5×5×5 cube = 35.767, with the largest produced 17×17×17 cube = 234.874 and the theoretical 22×22×22 model = 360.542. Obviously the decimals are a bit ridiculous, so we can instead say it progresses 14, 19, 27, 36 ... 235, 361.

It does at least, however, work in a sensible fashion for a 1×1×1 cube, giving an answer of zero moves (!) in order to solve it. Which is self evident, given that no "moves" are actually possible, and the cube is always solved.

trivia - did you know that the special symbols like × and ♥ appear to take up 3 bytes/ASCII character spaces, not the expected 2 of Unicode, at least when inserted into the edit summary? Maybe it's a UTF8 thing or something? 51.7.49.61 (talk) 00:32, 9 September 2017 (UTC)

That isn't meant to give you exact answers, see Big O notation. It expresses the way size of the solution grows with n, not the actual numerical size of the solution. Nobody curently knows the exact size of the maximum optimal solution for the higher order cubes. SpinningSpark 00:14, 10 September 2017 (UTC)

There are a few new records for the fastest non-human-solving time. The current one is 0.38 seconds (http://build-its-inprogress.blogspot.nl/2018/03/the-rubiks-contraption.html).

This beats the old time of 0.637 seconds (https://www.youtube.com/watch?v=N1b6iPYj3YQ)

That time beats the entry that is currently in the Wikipedia page.

Could the current entry for the fastest non-human-solving time be updated from 0.887 by the Sub1 bot, to 0.38 seconds by the Rubik's Contraption? And add the previous (0.637) record after that?

So change this:

The fastest non-human Rubik's Cube solve was performed by Sub1, a robot made by Adam Beer, an economist and industrial engineer. A YouTube video shows a 0.887-second solving time using an Arduino with the Kociemba algorithm. Next record is 3.25 seconds, set by CubeStormer III, a robot built using Lego Mindstorms and a Samsung Galaxy S4.[86] This beats the prior 5.27 seconds, set by CubeStormer II, a robot built using Lego Mindstorms and a Samsung Galaxy S2.[87] This had in turn broken the previous record of 10.69 seconds, achieved by final year computing students at Swinburne University of Technology in Melbourne, Australia in 2011.[88]

to this:

The fastest non-human Rubik's Cube solve was performed by the Rubik's Contraption, a robot made by Ben Katz and Jared Di Carlo. A YouTube video shows a 0.38-second solving time using an Nucleo with the min2phase algorithm. Next record is 0.637 seconds, set by Sub1, a robot made by Adam Beer, an economist and industrial engineer. A YouTube video shows a 0.637 second solving time. This improves the robot's old record: 0.887 seconds, performed using an Arduino with the Kociemba algorithm.

Please add an area in the "Competitions and Records" section (section 7) to cover robotic speedcubing, as for some reason this is not currently present. I will list all the references needed below, followed by some suggested sample text at the end of this message. First, the references:

Here are two articles on the most recent record set in this area, a solve in 0.38 seconds:
https://techcrunch.com/2018/03/07/this-robot-can-solve-a-rubiks-cube-in-38-seconds/
https://arstechnica.com/gadgets/2018/03/homemade-robot-smashes-rubiks-cube-record-with-0-38-second-solve/

Here is a link to the previous record, a solve in 0.64 seconds (this previous record is also referenced in the second article above):
https://www.livescience.com/56828-robot-sets-rubiks-cube-world-record.html

All the technical details of the new record-holder's Rubik's Cube solving robot can be see at these two blog entries of the creator's personal / project blogs:
http://build-its-inprogress.blogspot.com/2018/03/the-rubiks-contraption.html
http://blog.cactus.zone/2018/03/rubiks-solver-software.html

Finally, here is my suggested sample text to add to the Wikipedia article under section 7, "Competitions and Records". I am putting this text in bold to distinguish it from my previous text, but it should be formatted just like the rest of the page:

Robotic Speedcubing

Robotic solutions to solving Rubik's Cubes have resulted in multiple robots which can solve the cube (including imaging, determining a solution, and then making the appropriate moves) in less than a second. The designers of the two most recent record holding robots are:

Albert Beer, Infineon - 0.64 seconds

Odd sentence

"... and the red, white, and blue are arranged in that order in a clockwise arrangement"

Since the location of each color relative to the others is given, this statement seems unnecessary. But if someone feels it is necessary, then it needs to be further qualified. The statement is ONLY true if one of these three color is placed on top, with those three colors facing the viewer. In any other orientation, the arrangement of red, white, and blue is NOT necessarily clockwise.

Should probably be fixed. — Preceding unsigned comment added by 70.89.176.249 (talk) 01:30, 14 March 2020 (UTC)

Hi, DBaK. if a word is a noun, you need to write the first letter is Capital form. If it is not a noun, then the first letter should be in small form. So, since the word cube is a noun, it should be written as Cube. Also, if you look at the article about the Rubik's Cube, the word cube is always written as Cube. So, You have to write cube as Cube. Hope it helped! — Preceding unsigned comment added by Anonymous Cuber (talk • contribs)

@Anonymous Cuber: English does not generally write nouns in upper case, only proper nouns. "Rubik's Cube" is considered a proper noun so it's upper case. I think "Cube" or "cube" by itself depends on context with many unclear cases. If it's basically short for "Rubik's Cube" then it's sort of a proper noun and "Cube" seems natural. If it's used more as a normal word then "cube" seems more natural. I would have used "cube" more than the article currently does but English is my second language and I'm not making changes when it's unclear. If it's not about Rubik's Cube or another specific brand like in "other brands of cubes appeared" then it's definitely "cube". PrimeHunter (talk) 13:22, 4 January 2021 (UTC)

Pentangle

Do be aware that Pentangle was a very small company, and no large scale sales of the Magic Cube were envisaged - there was no plan for a mass market. Politechnika was not geared for it, and there were no mass sales or major impacts on mainstream pop culture in the UK caused by the Magic Cube. It would be wrong to infer that the UK was enjoying the Cube craze before the rest of the Western World. There simply were not the numbers of Cubes or the publicity. A guide to completing the Magic Cube was published in England by a small Norfolk publishing company in 1980.

(86.177.162.154 (talk) 18:46, 29 November 2022 (UTC))

I'm not sure which guide you are referring to. In France, the magazine "Science & vie" published about 4 articles about the Rubik's cube in the 1980s. If my memory is correct, one was about God's number being 20, another had an algorithm to rotate 2 corners in 16 moves. I remember that detail clearly because I knew it wasn't optimal. By removing the 1st and last moves which cancelled each other, it could be done in 14 moves. I'm sure there was other articles in other publications around the same time. Dhrm77 (talk) 19:45, 29 November 2022 (UTC)

'A Simple Guide To The Magic Cube', by Bridget Last, published by Tarquin Publications of Diss, Norfolk, England, in 1980. It was a small publishing company - and the book is probably as rare as Pentangle-distributed Magic Cubes. I still have the book somewhere. You can see more about it via the link to my '80s Blog at the end. I also have one of the Hungarian Magic Cubes distributed by Pentangle, before the great renaming, remanufacturing and then the mass manufacturing of the Rubik's Cube in 1980. My Magic Cube is somewhat heavier and rather more delicate than the 1980 version.

I don't have any sales numbers. I learned about the "Magic Cube" from an article in one of the UK's big Sunday newspapers, the Observer and the Sunday Times, I think in 1980, and bought myself a couple of cubes from Pentangle.

Section "Period of move sequences" is not correct.

In this section, it states the maximum period of a move sequence is 1260. This is wrong. The maximum period of a move sequence is 2520. I can name many sequences, for example: U F' M R' D F2. This sequence was found using my own simulator. This can also be verified in https://mzrg.com/rubik/ordercalc.shtml CYang11 (talk) 07:08, 25 June 2023 (UTC)

Typo request

For unknown reasons, the article is exempt from normal editing methods. Would someone please fix the typo in the "Permutations" paragraph (more specifically, its image explanation) where it says "corter" instead of "corner"?

Pedestal

Does anyone know when the pedestal (triangular stand) was first sold with the cube? Dhrm77 (talk) 14:28, 1 September 2023 (UTC)

The current world record of 3.13 is held by the USA's Max Park, who got the record on June 11 of 2023. The world record has changed a lot since the first record of 22.95 in 1982. The technology has also changed the original Rubik's Cube was made of hard to turn plastic and you could try to make it faster by putting chemicals that will temporarily allow it to turn faster by melting the plastic. Nowadays we have cubes that turn smoothly on their own and even have magnets in them. Who knows what innovation they will make next. D2-0n31 (talk) 16:27, 25 September 2023 (UTC)
