Oh, dude, there are like 26 letters in the alphabet, right? So, for each position in a 3-letter combination, you have 26 choices. That means you'd have 26 choices for the first letter, 26 for the second, and 26 for the third. So, the total number of 3-letter combinations would be 26 x 26 x 26, which is... math.

Not quite! This is the total number of permutations of 3 letters out of 26. AAB is counted as being different from ABA or BAA. But these are the same combinations.

Thus there are 26 combinations of just one letter.

26*25 combinations of two letters and

26*25*24/(3*2*1) of three.

In all, that makes 26 + 650 + 2600 = 3276
