add name-main idiom so the code can be imported as a library from other python programs

Jul 14, 2018 at 22:18 comment added Tony Ruth Thanks for reviving this question, and your answer looks pretty impressive. I like the recursive nature and the star figures. I connected your code to some opengl for drawing polytopes (see github link above).

tweak wording. (previous edit, for reference in case they get merged: speed up from quadratic to instant by using hacky string key hashing; change tol to 1e-9 because error does accumulate to about 1e-12 for the large polychora)

didn't need to say "(not 2)" any more since no part of the code uses edge length 2 any more

error on fraction with too many slashes, like 5/2/2

think in terms of more familiar dihedral angle instead of external dihedral angle (they are complements of each other)

use 5/2 instead of 2.5, add hyperlinks

correct description of xform matrix dims (should be dim x dim+1 instead of dim+1 x dim)

mention that elements do come out in some rough order, and the implications for infinite tilings

simpler dihedral-based calculations instead of black magic, reducing num lines from 99 to 89

I think I like "xyz space" better than "xyz subspace"

woops! forgot to actually make the tweaks to the code last time.

minor tweaks to make it work for star polytopes, and writeup
