[sage-support] Permutations with itertools.chain

Hello helpful sage-support list! Is this the following normal behavior? sage: import itertools sage: for x in itertools.imap(Permutations,range(4)): : for y in x: : print y : [] [1] [1, 2] [2, 1] [1, 2, 3] [1, 3, 2] [2, 1, 3] [2, 3, 1] [3, 1, 2] [3, 2, 1] sage: for x in it
