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.
