New issue 3480 by [email protected]: LeviCivita should canonicalize
http://code.google.com/p/sympy/issues/detail?id=3480
Currently,
LeviCivita(i, j, k) == LeviCivita(k, i, j)
False
but this should be True. Basically, LeviCivita should either move the
argument with the smallest sorting key to the first position, or sort its
arguments and multiply by a factor of -1 if necessary (if the new ordering
corresponds to an uncyclic permutation of the original ordering).
