Comment (by vdelecroix):
Indeed! Modifying the `__iter__` function in `PermutationGroup_generic` I
got
{{{
sage: timeit("for x in A: pass")
5 loops, best of 3: 116 ms per loop
}}}
Instead of
{{{
sage: timeit("for x in A: pass")
... still waiting
}}}
Do you know why the `list` method in the same class is cached?
