How many differrent ways can you arrange the letters of the word revolver?

Revolver has eight letters. Assuming you do not care if you make Words, there are 40,320 permutations for arranging those eight letters, if you do not count the repeated e's and v's and r's

8! = 40,320 = (1 x 2 x 3 x 4 x 5 x 6 x 7 x 8)

We must take this result and divide out the repeated elements. Since there are 2 e's, 2 v's and 2 r's:

40,320/(2!2!2!) = 5040.
