4 permutation.

$$4! = 4 * 3 * 2 * 1 = 24$$

mhchen · Answer

There are 4 letters. So that would be 4!.

If there were REPEATING LETTERS.

Example:
   SOONG

This would be 5 letters (5!) 'pronounced 5 factorial'
And you would divide by 2!  for the repeating OOs.
$$\frac{5!}{2!}$$

If there were MULTIPLE REPEATING LETTERS:

Example: 
   SSOONNN

This would be 7 letters, so it would be 7!
And you would divide by 2! for the SS, 2! for the OO, and 3! for the NNN.
$$\frac{7!}{2!2!3!}$$



Trust me, you're gonna get tested over these as well and my teacher tried to mindblow my class which made it really confusing :(
