So what you want to do is like shuffling a deck of cards, but you only have
15 cards.
The way I always handled that kind of thing was to make an array of the
right length (N=15), initialize it with identity values (so array[1] = 1,
array[2] = 2, etc). Then write a loop that goes from 1 to N. In the loop,
generate a random number from 1 to N and swap the array value at the current
loop index with the array value indexed by the random number. Each run
through this loop is a "shuffle". To get a nice randomization, shuffle the
deck seven times.

Yes,
I just need to be able to generate them and choose 40 random combinations.
I don't need to actually buld a table with
1,307,674,368,000 rows.

BTW you know there are
1,307,674,368,000
