# Good luck counting them all

How many different regular pair-wise non-similar $$2^{74207281} -1$$ sided polygons with fixed side length exist if self-intersecting is allowed?

Express your answer in form $$2^{n} - 1$$, submit $$\varphi(n+1)$$. (Euler's Totient Function of $$n+1$$)

Note: $$2^{74207281} -1$$ is the largest known Mersenne Prime.

Bonus: Generalize this for any number of sides.
