I am having trouble that my parents are being assigned in a category of finite
dimensional modules and the culprit seems to be this:
sage: M = CombinatorialFreeModule(QQ, DisjointUnionEnumeratedSets([Integers(),
Family([])]))
sage: M.category()
Category of finite dimensional vector spaces with

Sage freed me from the frustration!

I would like to vote for exponentiation for a right group action. This is
standard mathematical notation (as has already been said), at least in
several fields that I know of. Using the shift operators looks too much
like a computer-sciency solution to me. Sage has always tried to keep its
n
