Permanent[] is a built-in function, but it is not very fast. You might want to look at the solutions here.

comment Simple Enumeration of Coin Tosses
"it does not stop for cases where 4 heads or 1 Tails and 4 heads occur." - Tuples[list, n] will only generate lists of length n, so where would "4 heads or 1 Tails and 4 heads" come from?

comment How to solve an equation system whose equations are based on Mod[x,y]
I was staring at your answer for a while, and it suddenly clicked that you had written an answer before on the old AffineRationalize[] function. :) In any event, did you see the paper I linked to in a comment in the OP?
