From: Mike on 13 Oct 2009 21:59 Does anyone have some simple code to give all the permutations of an array of symbols? i.e. for two symbols in an array: my @array = ('howard', 'geek'); my @permutations = &permute(@array); print join(' ', $permutations[0]), "\n"; print join(' ', $permutations[1]), "\n"; howard geek geek howard It looks easy for two symbols. What about three, four, or more? Mike perl 5.8+

Sure enough, after posting the question I find an acceptable answer. The tsc_permute looks more simple. <http://docstore.mik.ua/orelly/perl/cookbook/ch04_20.htm> Mike
