This patch provides an implementation of the subword complex:
Fix a Coxeter system (W,S). Let Q = be a finite word in S and pi in W.
The subword complex Delta(Q,pi) is then defined to be the simpl…

The boundary of polytopes are nice and relatively well-behaved cell complexes.
When the polytope is simplicial, its boundary is a simplicial complex. This ticket implements a method to return that …

This is fairly unlikely but occasionally comes up on the buildbot:

Right now, our `generators` are divided into 3 files: `classic`, `uniform`, `nonuniform`.
I see a few disadvantages. In `classic`, I feel like we've started putting everything that's not "purely ra…

After a discussion at Sage Days 64, we decided to implement a variety of categories pertaining to geometry and topology to lend assistance to [SageManifolds](http://sagemanifolds.obspm.fr) (#18528) …

Sage's CHomP interface is out of date: the executables now have different names and may use a different syntax. Also, CHomP has not been updated recently — the most recent changes at https://github.…
