Good point. My comment was motivated by the high proliferation of AffineMap and permutation utilities over the years (to the point that sometimes it's a challenge, even for people familiar with the code, to figure out if something exists already). However, I think this adding this one is justified as it's combined with other utilities that work on permutations.
