Well, you talk about picking three files at random at once, but then you also say "until all combinations have been covered". Which means that what is really random is only the order in which you do things but that does seem mostly unimportant to me. If it actually is, then you may look up some combinatorial module on CPAN.

Said this, there are 7140 ways to pick 3 items out of 36, in which case you will have 7140 output files having a lot of redundant content each other. Is this what you really want?!?
