You link to a discussion of permutations but the original poster requested combinations
and it appears to me that the code here does find combinations (though I didn't fully digest the code so I could be wrong). Update: But actually running the code (modified so that I don't need the mentioned module) shows that it is finding permutations. *sigh* (:
Confusion between these two is not uncommon. See (tye)Re: Permutations for another instance and a bit of explanation of how to tell the two apart.
(but my friends call me "Tye")
