If the sequence is important, then there are (12 x 11 x 10 x 9 x 8) = 95,040 different ones.
If only the members of the group are important but not their the sequence, then
there are
95,040 / (5 x 4 x 3 x 2 x 1) = 792 combinations, each with different members.
The formulas are:
Permutations = 12! / 7!
Combinations = 12! / (7! x 5!)
