I see. Well I'll just say that the answer to a) is 256. If you want to, try solving again see if you get the correct answer. Solving by subtracting? Weird. One easy way to do it just to add the number the of permutations who consists of cycles of length 4,2 or 1. Same for b) where it's just 1,2,3,6.
