This is a precursor to #30680, laying out the framework for finitely presented modules over graded connected algebras. #30680 will focus on the case of the Steenrod algebra, with specific applicatio…

This provides an implementation of a slight generalization of the quantum Clifford algebra introduced by Hayashi with a general twist parameter `k`.

This is just to document the issue since I've seen it several times. It occurs just as the docs are being built. Perhaps parallel build related.

Now that `.op` is generally the vectorized form of `op`, it's very confusing that `.'` means transpose rather than the vectorized form of `'` (adjoint, aka ctranspose). This issue is for discussing al…

Do you have any examples of using the chain rule, for (automatic) differentiation?

Goal: implement a signed version of (co)product structure on tensor products of graded (or super) (co)algebras. We should be able to define superalgebras `A` and `B` and specify that when they are …

I see that you've made it possible to use REDUCE for symbolic manipulations, but I was hoping to be able to use sympy. I tried the obvious thing:
```julia

It might be nice to consider more exotic algebras and categories. Lie and Clifford algebras, groupoids, lattices, etc. I'm not sure any of these are necessary but if someone is excited to work on them…
