## Homework Equations

Circular Permutation problem

## The Attempt at a Solution

]I did 10!/5!5!=252

but from there I didn't get anywhere.

I know this includes repeats from rotational symmetry and reflections. but i am not really sure how to get rid of these.

i try dividing by 10 but it gives 25.2, which does not make sense to me.
