Hello,
Sorry I didn't get in on this sooner -- I've been really busy with
things this past week. Anwyays, CombinatorialAlgebra is getting a bit
of an update, and the changes are on the sage-combinat patch
repository. You can see a working group ring here:

If you attach a file containing
##

return PermutationGroupRing_generic(R,G)
class PermutationGroupRing_generic(CombinatorialAlgebra):
