Correct me if I'm wrong, and we'll move on from there. You want to take a sequence of 32 numbers and see if it's exactly the same sequence as some others. The easiest way to do this is with a tuple, rather than a list; then you can simply do an equality check, and they'll be checked recursively. If you want to ask, more simply, "does this 32-value unit exist in my collection of 256 acceptable 32-value units", then a set will serve you well. You can stuff tuples of integers into your set, and then query the set for a particular tuple. Does that help at all? If not, guide me to the problem you're actually solving. :) ChrisA
