I forgot to give a single example: The first CoxeterGroup is my implementation using chevie, everything after is purely in Sage. sage: W = CoxeterGroup(['H',3]) sage: M = W.cartan_matrix() sage: M [ 2 E(5)^2 + E(5)^3 0] [E(5)^2 + E(5)^3 2 -1] [ 0 -1 2] sage: DD = DynkinDiagram(M) sage: RS = DD.root_system() sage: SP = RS.root_space() sage: SP.weyl_group().cardinality() 120 sage: len(SP.roots()) 30 -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
