Combinatorics

As a first question: Eight children are in a carousel. Determine how many ways they can change places with the following condition: each child must have a different child in his/her right in the next permutation.

I'm having trouble with this one. Can anyone help?

Re: Combinatorics

Are the seats in the carousel different from each other? Or are they identical?

Re: Combinatorics

They are identical. The carousel only implies that they are siting in circle, so we would have to disconsider their rotation in the account.
