Hi I was wondering whether there is any current version of a calculator for Coxeter-Weyl root systems etc. Concretely all I am trying to do is to calculate the reduced Bruhat order on certain (parabolic) quotients of symmetric groups, so I do not necessarily need the full machinery. But naively using the "length" function etc on elements of the symmetric group does not seem to work, and references on the web to "Chevie" and "Weyl" packages seem to be defunct ...
Many thanks in advance Gary _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
