Coxeter's appendix to Regular Polytopes lists them in pairs to make duals stand out. Is there a way to make some of the horizontal rules heavier than others? --Anton Sherwood 17:57, 10 January 2006 (UTC)

First attempt: Row colors added, gray=self-Dual, red/blue pairs for duals

I think I can make a blank row with tiny height black as well, but not tried yet

I'd like to add information about existence - WHY these 16 exist and why other {p,q,r} permutations don't.... Help is appreciated. Tom Ruen 20:53, 11 January 2006 (UTC)

Coxeter's Regular Polytopes §7.7–§7.8 explains it, but it's a bit over my head. --Anton Sherwood 23:27, 11 January 2006 (UTC)
