Comment (by aschilling):
My timings before the patch::
{{{
sage: %timeit spin^3
5 loops, best of 3: 539 ms per loop
sage: %timeit spin^4
5 loops, best of 3: 6.31 s per loop
}}}
and with this patch::
{{{
sage: %timeit spin^3
5 loops, best of 3: 25.3 ms per loop
sage: %timeit spin^4
5 loops, best of 3: 126 ms per loop
sage: %timeit spin^5
5 loops, best of 3: 842 ms per loop
sage: %timeit spin^6
5 loops, best of 3: 520 ms per loop
}}}
This is definitely a huge improvement!
