The article is new enough and long enough. It is neutral and cites many reliable sources. I like the mixture of pure math and applications. There are no copyvio concerns. Hook fact is accurate, cited and neutral. I find it interesting enough, and using a very application-oriented hook should make it more appealing to a wide audience than going for the pure math options. QPQ has been done. Good to go. —Kusma (t·c) 23:21, 26 April 2021 (UTC)[reply]

Image caption

In the caption for the first image on a page, it says " there are 69 interior dots.." and because of the number, I just wanna make sure that it wasn't vandalized and that it just happened to be that number. Blaze The Wolf | Proud Furry and Wikipedia Editor (talk) 17:54, 8 May 2021 (UTC)[reply]

So count them. You know how to count, I assume. —David Eppstein (talk) 18:29, 8 May 2021 (UTC)[reply]
