There are 8 letters with no repeated letters and you are working out the number of combintaions of all 8 letters with respect to order so the answer is 8P8=8!=40320
product? four - 4 letters
The solution is count the number of letters in the word and divide by the number of permutations of the repeated letters; 7!/3! = 840.
Here P and S are fixed, so 10 letters are left, out of which 2 are T'sSo, 10 letters out of which 2 are T's can be arranged in 10!/2! = 1814400 waysNow letters P and S can be arranged so that there are 4 letters between them, which can be done in 2*7 = 14 waysRequired no. of ways = 1814400 * 14 = 25401600
