So far the face iterator for polyhedra assumes the diamond property of the lattice only. The special case of simple/simplicial polytopes is not exploited. In this case all intervals not containing z…

Sage now contains various lines of the form `from builtins import ...` which is provided by the `future` package.
Currently, `pyparsing` is needed for `src/sage/homology/simplicial_set_examples.py`…

As the summary says...
For possible follow-up tickets:
- simplicial abelian groups and Eilenberg-Mac Lane spaces.
- effective homology and related computations that Kenzo can do but we can't yet.
…
-
An upcoming version of Kenzo will include functions to compute homotopy groups.
This ticket will track the work to update it and the corresponding interface
The tarball of the new version is avai…

Add functionality to sage to compute the effect of a simplicial complex morphism on homology and cohomology.
This patch will rely on fuctionality in #6099, #6100, #6102, and #5882.
Depends on #191…

Finite dimensional modules over a finite field are known to Sage to be finite:
```
sage: Modules(GF(3)).FiniteDimensional().is_subcategory(Sets().Finite())
True
```
However this piece of k…

We add support for filtered complexes and persistent homology.
The algorithm implemented is described in 'Computing Persistent Homology' by A. Zomorodian and G. Carlsson.
