Speed: Prime is the big big winner. 1'51s to find the result! Amazing. You cannot even compare with old gen calculators.

Can you confirm the speed? 1 minute and 51 seconds on the Prime compared to 20 seconds on the 15C-LE is not so impressive.

I didn't transpose the 15C algorithm, I transposed the C++ STL next_permutation algorithm. I would rather compare this to the former 34s result, 48mn.

Not sure how the 15C algorithm works, isnt' it brute force?
