This patch should be applied -- doctests are excellent and I think the divides() function is good.
There is a typo:
1624 def divides(self, x): 1625 """ 1626 Return True if self divides n.
$n$ should be $x$.

- Resolution set to fixed
- Status changed from assigned to closed
Merged in 2.8.15.alpha1 - I corrected the documentation as Nick suggested.
