    26 letters in the alphabet.

    2 are already taken ( A and B)

    so for the first letter after A, there are 24 possibilities remaining

    next letter has 23 possibilities left

    letter after that has 22 possibilities

    etc

    so

    24 x 23 x 22 x21 x20 x19 x 18 = 1,744,364,160 possibilities
