Talk:257-gon

Names?

Potential greek prefix names for the 257-gon are dicosapentacontaheptagon or dihectapentacontakaiheptagon. [1]. Tom Ruen (talk) 03:17, 20 February 2015 (UTC)[reply]

Yes, but I think that if only one source derives this name, and the system it follows ("-hecta-" instead of "-cosi-") isn't even always followed, then we should not mention it as if it were a standard. Double sharp (talk) 03:26, 20 February 2015 (UTC)[reply]

The term "dihectapentacontakaiheptagon" is definitely wrong. 257-gon should be diacosipentacontaheptagon. The affix should be "-cosi-" instead of "-hecta-" above 200. The prefix "hecta-" is only for one hundred, never for 200-900.

Read the passage Greek Numbers and Numerals. It tells you that 100 is ἑκατόν (èkatón, hecato-), and 200 is διακόσια (diakósia, diacosi-), and 300 is τριακόσια (trikósia, triacosi-), ..., and 900 is ἑννεακόσια (ènneakósia, enneacosi-). Therefore, 257 is definitely διακόσια πεντήκοντα [καὶ] ἑπτά (diakósia penteíkonta [kaì] èptá), so 257-gon should be either diacosipentacontaheptagon or diacosipentacontakaiheptagon. --Yejianfei (talk) 10:22, 10 July 2019 (UTC)[reply]

Does this gif really help with the understanding of anything on the page? It's so long and quick-changing that it can't readily be digested. Is there not a guideline regarding the presentation of information that's being undermined here? — Preceding unsigned comment added by 195.249.185.2 (talk) 16:49, 15 May 2015 (UTC)[reply]

Right, slow down tenfold or remove. --Rainald62 (talk) 10:43, 10 June 2018 (UTC)[reply]

Done It was archived by archive.org. I have fixed the reference for you. The Quixotic Potato (talk) 23:50, 26 January 2016 (UTC)[reply]

@ The Quixotic Potato,

thanks, I have within WP for "DeTemple, Duane W. (Feb 1991). Carlyle circles and Lemoine simplicity of polygon constructions" searched. I have found still these pages:

(1) 65537-gon

(2) Carlyle circle

(3) Geometrography

(4) Thomas Carlyle.

Then, I have after your explanation the links corrected. --Petrus3743 (talk) 00:57, 31 January 2016 (UTC)[reply]

why does this have its own article?

why don't any other arbitrary gons have their own articles? 98.128.166.109 (talk) 01:10, 8 April 2022 (UTC)[reply]

The regular 257-gon is often mentioned in reliable sources because it's constructible (and also 257 is prime, so that doesn't just follow from constructability of a smaller regular polygon). Double sharp (talk) 10:08, 30 August 2022 (UTC)[reply]
