Hi Tomruen.
Thanks for the List of Coxeter groups.
I've yet to see a Venn diagram of groups information... is it possible?
Thanks,
Art Scott

G2, H3, H4
[edit]G2 is applied to the hexagon, the final of the polygons to have a integer shortchord-square. This corresponds to a Dynkin symbol with three bars connecting the two nodes (ie o===o , where = is really three lines, not two).
H3, H4 appear by Coxeter, to add symmetries that don't give rise to Lie groups, to wit {3,5}, {3,3,5}. Calling these G are likely to confuse. --Wendy.krieger (talk) 11:05, 11 January 2009 (UTC)
compact hyperbolic
[edit]I don't see [5,4] here ... —Tamfang (talk) 19:42, 24 July 2012 (UTC)
