Frederic, I pushed a patch (coxeter_ms.patch) to the sage-combinat server.
Now you should get sage: W=WeylGroup(['A',2]) sage: w=W.from_reduced_word([1,2,1]) sage: w.inversions() [alpha[1], alpha[1] + alpha[2], alpha[2]] which is much nicer. --Mark > Trying to use inversions for elements of Weyl groups, I found that it > exists, but does not work, and is badly documented and tested.
