A (4)

B(4)

C(6)

D(2)

E(6)

F(6)

G(4)

H(4)

Working down the list we can have A1, B1, C1, D1, E1, F1, G1, H1, then we change H to 2, then 3, then 4, then we change G to 2 and H to 1, then H2 etc.. until we eventually wind up with 44626644. I can't quite figure out how many different possible combinations there are, 8^36 gives a silly number, there is probably a really easy solution that I'm not quite getting, so any hints tips or even the solution?

Multiplying the numbers will give you the correct value of possible outcomes.

That's RPM to you!!
