| 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). | |
| Jul 5, 2018 at 23:20 | history | edited | Don Hatch | CC BY-SA 4.0 | clarify code comment |
| Jul 5, 2018 at 22:55 | history | edited | Don Hatch | CC BY-SA 4.0 | 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) |
| Jul 5, 2018 at 20:53 | history | edited | Don Hatch | CC BY-SA 4.0 | didn't need to say "(not 2)" any more since no part of the code uses edge length 2 any more |
| Jul 5, 2018 at 14:32 | history | edited | Don Hatch | CC BY-SA 4.0 | error on fraction with too many slashes, like 5/2/2 |
| Jul 5, 2018 at 14:26 | history | edited | Don Hatch | CC BY-SA 4.0 | fix comment |
| Jul 5, 2018 at 14:08 | history | edited | Don Hatch | CC BY-SA 4.0 | fix formatting and uncomment thing I accidentally commented out |

| Jul 5, 2018 at 14:05 | history | edited | Don Hatch | CC BY-SA 4.0 | think in terms of more familiar dihedral angle instead of external dihedral angle (they are complements of each other) |
| Jul 5, 2018 at 5:35 | history | edited | Don Hatch | CC BY-SA 4.0 | forgot one link |
| Jul 5, 2018 at 5:25 | history | edited | Don Hatch | CC BY-SA 4.0 | use 5/2 instead of 2.5, add hyperlinks |
| Jul 5, 2018 at 3:40 | history | edited | Don Hatch | CC BY-SA 4.0 | correct description of xform matrix dims (should be dim x dim+1 instead of dim+1 x dim) |
| Jul 5, 2018 at 3:22 | history | edited | Don Hatch | CC BY-SA 4.0 | mention that elements do come out in some rough order, and the implications for infinite tilings |

| Jul 5, 2018 at 2:52 | history | edited | Don Hatch | CC BY-SA 4.0 | simpler dihedral-based calculations instead of black magic, reducing num lines from 99 to 89 |
| Jul 4, 2018 at 13:50 | history | edited | Don Hatch | CC BY-SA 4.0 | I think I like "xyz space" better than "xyz subspace" |
| Jul 4, 2018 at 13:06 | history | edited | Don Hatch | CC BY-SA 4.0 | woops! forgot to actually make the tweaks to the code last time. |
| Jul 4, 2018 at 12:43 | history | edited | Don Hatch | CC BY-SA 4.0 | minor tweaks to make it work for star polytopes, and writeup |
