I'd like to confirm, what is the name of this combination, and if its calculated right:
Set (a,b) is spread over set of (1,2,3)
1 2 3 a b a1 b1 2 3 a1 b2 3 a1 2 b3 b1 a2 3 b1 2 a3 1 a2 b2 3 1 a2 b3 1 b2 a3 1 2 a3 b3
2*3 + 3 = 9
And based on that I'm doing it with a bigger sets without manual trial and error:
1 2 3 4 5 6 7 8 9 10 11 12 a b c d e f g
7*12 + 12 = 96
