The cyclic group $\displaystyle C_{n} $ is the group of n rotations that maps a regular n-gon onto itself. These rotations correspond to multiplying C by which n complex numbers?

If $\displaystyle \displaystyle\varsigma = \exp \left( {\frac{{2\pi i}}{n}} \right)$ then the complex numbers $\displaystyle \varsigma^k,~k=0,1,\cdots n-1$ will work.
