Hello,
Can someone help me figure this math. I have a bank of numbers. I have:

Twelve 1's
Twelve 2's
Twelve 3's
Twelve 4's
Twelve 5's
Twelve 6's
Twelve 7's
Twelve 8's

I want to randomly generate 3 digit numbers with the bank until the bank is empty. One limitation is none of the three digit numbers can have the same numbr in it twice .... like 223. And another is the same three digit number cannot be repeated, such as 345, 345.

Thank you,
Odisey
