lets say you have the word M-I-S-S
whats a quick way to determine the number of combinations of two letters you can create?

Simple combination formula would suggest 4C2, which is 6, but this is not the case since there are two S's, so the actual number of combos is 4:
MI, MS, SS, IS

total = 4c2 = 6
repetation = 2
so actual = 6 - 2 = 4

could you explain this part more:
repetation = 2
so actual = 6 - 2 = 4

What if the word contained more letters? say: ABCDDDEFGHHH?
Then how many unique combinations?
Thanks!
