I'm trying to look through every combination of a set that size and find an optimal solution.

2^80 == 1208925819614629174706176. If you could test 1 million per second, your task will take 38 billion (38,308,547,532) years!

Even if you only iterate those 80-bit values that have 7 .. 25 bits set, that is still 304202362464000 variations; and would take over 9 years at 1 million per second.

Update: That is still 636,339,175,131,064,539,743 variations (assuming no ordering requirement) which would take 20,164,371 years at 1 million per second.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority". The enemy of (IT) success is complexity.
In the absence of evidence, opinion is indistinguishable from prejudice.
