Hi Christian, Mark just pushed a patch (coxeter-ms.patch) which is in conflict with your patch applying trac_12882-generalized_cartan_matrix_as_dynkin_diagram_input-cs.patch applying trac_11187-finite_reflection_groups-cs.patch patching file sage/combinat/root_system/root_lattice_realizations.py

Hi Mark, I have been messing with the Littelmann patch (but not Weyl groups), so please go ahead. There is some stuff we need to fix there, but perhaps tomorrow when I am back. Anne On 5/19/12 9:32 AM, Mark Shimozono wrote: > Hi all, > > Is anyone messing with root lattice realizations or Weyl

Hi all, Is anyone messing with root lattice realizations or Weyl groups? I want to put in a few functions involving parabolic subsystems and the parabolic quantum Bruhat order. It will be done somewhat dumbly, that is, without developing morphisms of Dynkin diagrams and its consequences on thing
