In how many ways can the letters of english alphabet be arranged so that there are 7letters in between A and B and no letter is repeated?

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