July 5[edit]
How to categorize these images?[edit]
I recently uploaded these two images to supplement the four referenced in the Fundamental polygon article. What categories should I put them in? In particular, I don't know if they're actually fundamental polygons or not: it's been a while since I've proven that something is a closed surface. Jbeyerl (talk) 17:37, 5 July 2014 (UTC)
- It's not definite, but I lean against those ending up being manifolds. The group representation for the first would be A2 = 1, and the second would be A2B−2 = 1. — Arthur Rubin (talk) 01:17, 8 July 2014 (UTC)
