Template talk:Figurate numbers

4-dimensional problems

• Squared triangular numbers are non-central, in that they count the number of integer solutions of 0 ≤ a, b, c, d; a + b, c + d ≤ n. They might also be central by a different construction, but I've seen no evidence of it.
• Centered pentachoric numbers may need to go.

Partial collapse

Would it be possible to have only a single group expanded, using {{Navbox with collapsible groups}}? — Arthur Rubin (talk) 23:06, 21 December 2019 (UTC)

Higher-dimensional figurate numbers

Should fifth power, sixth power, seventh power, and eighth power be added to the template as higher-dimensional non-central figurate numbers? — Arthur Rubin (talk) 01:39, 27 December 2019 (UTC)

Done. If anyone objects, talk to me. — Arthur Rubin (talk) 22:37, 27 December 2019 (UTC)
