`trace::consolidate_by` and ord batch merging both implicitly assume commutativity of the difference type, because they accumulate `rhs += lhs`, rather than the other way round (see [here](https://git…

The following code with mixed commutative and non-commutative variables generates too many intermediate terms:
```
CF a;
NF d, e;
L A = (a+d+e)^10;
.end
Time = 0.03 sec Generated terms = …

Could we represent commutative diagrams in Catlab? Isn't a diagram `D` in category `C` just a functor `F: D --> C`. The data you pass to the `functor` function specifies a map from objects/homs of `D`…

Additional features to be added to various spectral classes:
- Spectrum:
-- Addition: applicable to collect and sum various spectral elements. -- Non-commutative New Spectrum = Spectrum1 + Spectru…

- [x] Find the most general scalar ring/field `k`
My impression is that a PID scalar ring could be enough.

I am adding some results on rings:
- [x] Ring ideal definition
- [x] Product and sum of ideals
- [x] Prime ideal definition
- [x] Maximal ideal definition
- [x] Spectrum and Zariski topology

We don't currently track `Blend` as commutative and so we miss an opportunity to ensure that "memory operands" always appear on the RHS: https://github.com/SixLabors/ImageSharp/pull/2359#discussion_r1…

Off the top of my head:
- [x] `patch` (so long as it has a `Group` class) (https://github.com/reflex-frp/patch/pull/39)
- [x] `groups` (https://github.com/Taneb/groups/pull/14)
- [x] `group-theor…

This is not a bug, because I cannot create reproduce link. Problem is very complicated to create small example and i am not able to share whole project.
## Context
We have entities linked with F…

Reported by email by Rene Marczinzik. This calculation reports that `U` is commutative, while it is not:
```
gap> G:=QuaternionGroup(8);
gap> R:=GroupRing(Rationals,G);
