It's not in the trac, but you can view the patch at the URL that I posted. My intention was to make a trac ticket after perhaps some comment by others, especially the sage-combinat-devel people. It's based on GAP in that WeylGroup_gens is a derived class of MatrixGroup_gens which is a wrapper for GAP's matrix groups. But it is independent of the Lie code in GAP but rather is based on combinat/root_system.py which is in turn the basis of combinat/crystals/ . I think that root_system.py together with combinat/crystals/ are nearing some point of completeness from the point of view of someone that needs to actually do calculations. The lack of Weyl groups was a gap (no pun intended).
