After #12817, almost all lemmas can move from Algebra.GroupPower.Ring to earlier files at no cost.

The few remaining lemmas could also move, but it would require a tiny bit more work.


Open in Gitpod

Move a bunch of `pow` lemmas from `Algebra.Group.Commute.Defs` and `Algebra.GroupPower.Basic` to `Algebra.Group.Defs` and `Algebra.Group.Basic` with little to no changes to their proofs.
After #12736, `powMonoidHom` and `zpowGroupHom` can move to `Algebra.Group.Hom.Basic` at no cost. This PR moves them and deletes the now empty `Algebra.GroupPower.Hom`.
After #12817, almost all lemmas can move from `Algebra.GroupPower.Ring` to earlier files at no cost.

The few remaining lemmas could also move, but it would require a tiny bit more work.
