Hi folks,
Gregory McWhirter has put a lot of effort into upgrading the NetworkX
spkg to version 1.0.1. At ticket #7608 [1] is a (roughly) 500 KB patch
to the Sage library and an upgraded NetworkX spkg.
Hi Bjarke,
If I understand your goal, this could be a typical use case of generic
category testing. Whenever you have a monoid M and you run:
sage: TestSuite(M).run()
the associativity of M is tested (by M._test_associativity()). We do
not yet have a PolynomialRings category,

Shameless plug: there is some work in progress in that direction,
providing a standard architecture for implementing a quotient or

ready for integration into Sage, but we will be using it intensively
soon. In short, the idea

For our upcoming French Sage book, I just added a new sageexample

So it's a Pari bug. I see. I guess I was misled by the fact that the
