--- Comment #2 from Wyatt <wyatt....@gmail.com> --- I guess it might? It looks about how I had envisioned it, but I'm not really jazzed about the idea of installing an entire mathematics package for a one-off script I was expecting to take fifteen minutes. As for the reasoning, I just figured this was obvious? I mean, there probably isn't an introductory text on permutation that doesn't cover the constrained case. --
