GAP is very cool to work with permutations. But this is not possible to be as smart in Sage as (1,2,3) is a tuple. > Yes, I must agree that in Pythonic world > sage: Permutation((1,2,3)) > > must be equal to > sage: Permutation([1,2,3]) +1 It would be particularly dangerous to have different behavior in that case (think about the semantic of an iterator that changes from iterating through list to iterating through tuples). > And if you mean the cyclic permutation (1,2,3) this should be > sage: Permutation([(1,2,3)]) +1 Vincent -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
