It's a branch and bound-algorithm, by early cutting unnecessary branches I avoid calculating all permutations, which is (far╣) more efficient.▓
And it gave me the opportunity to check some mathematical approaches (which are more challenging for me)
But you're welcome to show us your way to do it!(BTW: I saw your approach already been done in Python, if you're interested)
╣) since 8! is only ~40000 it's not too obvious in this special case.
▓) Furthermore branching allows to cache/memoize results for subtrees to go even faster.
