I just need a clever way to do the search to reduce the number of checks for the cases where they don't match or there are large sets involved.

There can't be large sets involved.

A tiny little set with only 100 elements has a power set of size 2^100. It would take 952,589,676,412,928 GB just to store a bit vector of that many elements.
