As some other poster already suggested 'powerset' (
http://en.wikipedia.org/wiki/Power_set ) may be a better name, except
for those duplicates, of course. On the other hand, I think viewing it
as a powerset is the most 'natural' in this case. (imo permutations are
about the order of objects, not about whether the objects are included
in a set or not)
