basic math.
3 * 36 = 108
108 different combinations, if I did this correctly. |

| Thanks for correcting me, I wasn't sure if I was right. 108 didn't seem large enough. |

It actually depends on the criteria.
Duplicate letters allowed? EX: aaa Combinations = 36 ^ 3
Duplicate letters not allowed and order matters? EX: abc =/= acb =/= bac =/= bca =/= cab =/= cba Combinations = 36 * 35 * 34
Duplicate letters not allowed and order does not matter? EX: abc == acb == bac == bca == cab == cba Combinations = 36! / (3! * 33!) = (36 * 35 * 34) / (3 * 2) = 35 * 34 * 6 |
