View on Github →refactor(group_theory/general_commutator): Rename general_commutator to subgroup.commutator (#12308)
This PR renames general_commutator to subgroup.commutator.
I'll change the file name in a followup PR, so that this PR is easier to review.
(This is one of the several orthogonal changes from https://github.com/leanprover-community/mathlib/pull/12134)
