Factorial : There are n! ways of arranging n distinct objects into an ordered sequence.

With 80 objects,

n! = 80!
= 7.156945704 E+118

There is no program/computer that can do that many tests. This is a humongous number.

You have absolutely no chance at all without a strategy to reduce the number of tests. A better explanation of what you are testing will probably yield massive orders of magnitude in reduction of computations. Without that, I see ZERO chance.
