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.
