Excellent! Also look at the combinatorics functionality in MAGMA and Maple... > I was wondering the best way to go about integrating these changes > into SAGE, specifically naming conventions.

Yes, that would help a lot to not pollute the global namespace too much. Alternatively, all functions on permutations could be methods on PermutationGroupElements, which are defined in sage/groups/perm_gps/. This would be a nice way of unifying things a bit more, and would make a lot of sense.
