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…

Simplicial complexes are lacking a proper hash function. See the example below.
```
sage: S = SimplicialComplex([[]]); S
Simplicial complex with vertex set () and facets {()}
sage: hash(S)

Rationale : R (standard package) requires libpcre (in a non-default configuration), but stopped to package it with version 3.3.0.

For simplicial toric varieties, the rational cohomology ring and the ratironal Chow group are isomorphic. So if all normalizations are correct, then one should be able to do intersection computation…

In #30181, the class `ModuleElementWithMutability` was introduced. In an effort to set a standard in Sage, as per `sage.structure.mutability.Mutability`, we rename the `_is_mutable` to `_is_immutabl…

There is a doctest in `sage/structure/sage_object.pyx` to verify that all objects in the pickle jar can be unpickled to some Python object without raising an error, but that is about it as far as ch…

Permutation groups used to support only 1...n elements, but that is not the case anymore. We can return automorphism groups that do not need to be relabeled, and that is GREAT `:-P`
