Comment:
Just for reference: turns out there was
[https://groups.google.com/forum/#!topic/sage-devel/r38j4epfogs quite a
discussion] on 0-based permutations and some probably poor design
decisions early in Sage's life (i.e. `Permutation([1,2,3])` and
`Permutation((1,2,3))` not being the same thing, where probably the latter
should have been required to be `Permutation([(1,2,3)])` so the cycle
notation didn't get confused with other notation. Anyway, for now I'm
putting this on "needs info" since I didn't see a lot of consensus on
sage-devel.
