Reason for move[edit]

Both the OEIS and Mathworld refer to this numbers as "pentatope" rather than "pentatopic." (Actually, the primary name given by the OEIS is "Binomial coefficients binomial(n,4)." PrimeFan 20:04, 14 Apr 2005 (UTC)

what?[edit]

after reading this article, i still have no idea what sort of geometric pattern produces this number sequence.--Jeiki Rebirth 18:49, 22 September 2006 (UTC)[reply]

Have you looked at the picture? Does the picture make it clear or is it confusing? PrimeFan 00:06, 23 September 2006 (UTC)[reply]

The picture is entrancing but confusing, and doesn't really have a very helpful explanation. It seems to imply that four dimensions are needed to represent the relevant picture? Dranorter (talk) 23:18, 21 June 2009 (UTC)[reply]

Requested move[edit]

Polychoron means 4 dimensions; polytope means any number of dimensions. The article for the figure itself is at Pentachoron, not "Pentatope", so the article for a kind of number based on it should be titled similarly. Georgia guy (talk) 16:56, 11 October 2008 (UTC)[reply]

Unsure. It's an inherently technical article, so perhaps such naming considerations are appropriate. But is there any evidence that this more precise terminology is widespread among those who use the term? I'm tending to the weakest possible oppose on the grounds that a case hasn't yet been made.

Weak oppose, too. It seems that many people use "pentatope" synonymously with "pentachoron" (e.g. mathworld, and the wikipedia page). Also, Google returns NO hits for "pentachoron number" (versus ~1000 for pentatope number). 87.114.147.211 (talk) 20:28, 11 October 2008 (UTC)[reply]

Another weak oppose. An OEIS search for "pentatope" gives 20 results, while "pentachoron" just one. But the cited OEIS sequence (sequence A000332 in the OEIS) calls these numbers "Binomial coefficients binomial(n,4)," not "pentatope" nor "pentachoron," though these words do come up in Michael J. Welch's comment to the sequence. PrimeFan (talk) 23:21, 11 October 2008 (UTC)[reply]
