Talk:Nine-dimensional space

our little redirect has grown up into a stub article

 * Okay, but why? What can be said about 9-space that makes it distinctive from 8-space and 10-space and n-space? —Tamfang (talk) 20:46, 28 November 2016 (UTC)


 * That it has nine dimensions? Other than that, I don't think that studying n-dimensional space where n > 10 is going to be qualitatively different for different values of n, so IMO the current system (which covers everything up to 11-dimensional space, and none more) is fine as is. (FWIW, I also rated this article as low-importance, similarly to Four-dimensional space and Five-dimensional space.) Duckmather (talk) 21:11, 21 May 2021 (UTC)

uniform figures
Given that the polytopes section lists one uniform nonregular, how about mentioning the rest of them?
 * 271 in group A_9
 * 511 in group B_9 (what Regular Polytopes calls C_9)
 * 128 (nonredundant) in group D_9 (what Regular Polytopes calls B_9)

And for tilings of E^9, we have
 * 527 in the cubic group
 * 256 (nonredundant) in the alternated cubic group
 * 36 (nonredundant) in the doubly alternated cubic group
 * 77 (how many redundant?) in the loop group

. . . without getting into products. —Tamfang (talk) 06:01, 16 May 2017 (UTC)
