You're asking for a canonical representation, which amounts to a canonical choice of a defining polynomial for the field. One can sort defining polynomials and choose the "smallest" one that gives a field isomorphic to your field; this seems to be more accepted for finite fields. I think you might just want to try set([1, 3, 2]) == set([2, 3, 1, 1]) and test for what you're really getting: a set.
