FindPermutation
FindPermutation[expr]
gives a permutation that produces expr by permuting Sort[expr].
FindPermutation[expr1, expr2]
gives a permutation that converts 
to 
for two expressions that differ only in the order of their arguments.
Details
- The permutation is returned with head Cycles, in disjoint cyclic form.
- If the arguments of
are different, the permutation returned is uniquely defined. - FindPermutation[expr2, expr1] gives the inverse permutation of FindPermutation[expr1, expr2].
