Comment:
I made a few changes:
- Added `coxeter_matrix()` to symmetric group so its some geneic methods
of its elements are not broken.
- Added a new class for elements of the symmetric group (the permutation
group element code could use a cleanup to bring it up to our current
standards; e.g., the first input for the element should be the parent and
we should use the category framework).
- Changed `dict` into dict comprehension.
- Added an absolute order example poset for Coxeter groups.
- Removed the size of `n` restriction for the symmetric group. It's
artificial and someone might want the `n = 11` case to test a conjecture
on a good machine.
If you agree with my changes, then you can set a positive review.
