Comment (by tscrim):
Some other things that would be nice:
- Make this into a permutation group (similar to `SymmetricGroup`).
- Add methods to transform elements into a `SymmetricGroup` elements via
the natural "diagram folding".
- Implement the even signed permutation group.
- Implement the natural coercions between the above.
I can also do (some of) the reviewing when this is ready too.
