Salut Nicolas, ok, tu as le feu vert pour modifier mon patch pour enlever la dependance. I think the method auslander_reiten_matrix should really be called *coxeter_transformation*, because this is the usual name. One speaks of the Auslander-Reiten functor, but this is not the same thing. Once

Hello! We have a heated debate on http://trac.sagemath.org/sage_trac/ticket/10140 regarding the following issue. When a user writes Cone(rays=[(1,0), (0,1)]) and the internal framework that eliminates unnecessary generators comes up with a cone generated by (0,1) and (1,0) (i.e. same rays but
