Ah, then that's easy. Sit down with pencil and paper, write out all 64 combinations yourself, and then type them into a Python list. Then you can access any one of those combinations with a single call. A lookup table is the fastest possible way for the CPU to give you the answer you want. [snip] > My list is not arbitrary.

That's good, since you only need combinations of "a", "b" and "c" the lookup table is quite small and manageable. I was worried that you might have wanted to apply your function to any set of items. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
