A permutation that lists n different elements in a circle is called a circular permutation, and the number of permutations is calculated as follows.

P = (n-1)!

If the permutation of n elements arranged in a row is changed into a circle, there are n permunation of a same rotation direction.

Therefore, the number of the circular permutation becomes 1/n of the number of permutations, and n! * (1/n) = (n-1)!.
