[Maxima-discuss] Permutations & Permutation Group Theory

[Robert S. <qu...@sy...>]

Hey all:

I wanted to let everyone know about the existence of the portable Common
Lisp library called CL-PERMUTATION that I've been chipping away at for a
while now. It allows for computations on permutations and permutation
groups. CL-PERMUTATION is located here:
https://bitbucket.org/tarballs_are_good/cl-permutation/ and it is licensed
as BSD 3-clause, so plenty permissive.

GAP is of course the main player in this game, and it's indeed a very good
package. However, it isn't so nice or easy to integrate into other
software, like Maxima, without introducing complicated or non-portable
dependencies. (With that said, it's likely to be more powerful than any
one-man effort.)

I think CL-PERMUTATION may be good for inclusion as a share package. If
someone decides to get started on such a thing, I would be happy to
contribute and help maintain the best I can.

Regards,

Robert Smith
