numbers of variables

1. i have three sets:-
(1) set 1 contains 6 names (one can use english alphabet to name them)
(2) set 2 contains 2o entirely different names (one can use 15th mongolian alphabet to name them, or whatever)
(3) set 3 contains 50 entirely different names (one can use 19th century swahilian cuneiform to name them, or whatever)
– a total of 76 different names

2. i need to find out the total number of variables:-
(1) within each set (variables include, for example, in set 1, A alone; D alone; the pair of A and B; the pair of A and C; the pair of A and D; the group of A, B, D, F, etc)
(2) between every variable within set 1 and every variable within set 2
(3) between every variable within set 1 and every variable within set 3
(4) between every variable within set 2 and every variable within set 3
(5) between every variable within set 1, every variable within set 2 and every variable within set 3
