  • Version 1.3: Updated to scribble docs, new srfi-42 implementation, and added PLT iteration generator in-permutations.
  • Version 1.2: Fixed documentation bug.
  • Version 1.1: Fixed documentation and contract bug with permutation-next! and permutation-next.
  • Version 1.0: Uses relatively simple (and sub-optimal) algorithm for generating permutations. Let me know if you need better.

    Currently uses a simple algorithm from Knuth (see permutations.ss source for more details).Please let me know if better algorithmics would be useful in your application.
