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);
gap> W:=WedderburnDec…

Problem name: Unionfind with Potential
## Problem
Given a graph with $N$ vertices and $0$ edges, each vertex have some weight $w_v$ on it. Process the following $Q$ queries in order:
- $t_i =…

+, *, =, and & are all examples of commutative operations. In pySMT we treat the expression `a = b` as a different expression than `b = a`. This is because we do not try to normalize the order of the …

JoinSemiLattice requires that join is commutative, but this is not necessarily true for the instance JoinSemiLattice (Set a) where join = union.
Consider this valid total order:

### Description
Not sure how this classifies but since it's likely to have been discussed elsewhere, let's take it as a doc improvement.
`pl.col()` can be mixed with the `polars.selectors` API and…

I recently found this library and found it to be very useful and wish I knew about it years ago.
Is it possible/easy to implement `aac_congruence` using the machinery defined here?
For example, befo…

I've been wanting something like a "commutative cryptographic hash function" (or just a "rolling cryptographic hash function") that would allow us to compute a cryptographic hash of some data `M` give…
