there are 9 letters, so the total number of permutations is 9!. However, there are 4 e's and 2 n's, so these repetitons need to be incorporated to reduce the number of permutations, since seventeen and seventeen are the same word but with the 2 n's swapped around.

So, final answer is 9!/(4!2!) = 9x8x7x6x5x4x3x2x1/(4x3x2x1x2x1)
--> 9x8x7x6x5/2x1
--> 9x4x7x6x5
--> 7560
