Permutations now work from R to L in Permutation and Cycle form. lmul is the public classmethod to do otherwise: Permutation.lmul(a, b) = b*a
What does anyone think about always storing a permutation in array form? It can be viewed in cyclic_form with the cyclic_form method (or converted to a Cycle with Cycle). This would clean up the instantiation problem now that arises because if the whole cycle is not stored then you need two args (cycles and size) to reconstruct as Permutation(*p.args) and right now, size is not being stored as an arg. /c -- You received this message because you are subscribed to the Google Groups "sympy" group.
