High symmetric n-polygons
Rolf Haag · arXiv (Cornell University) · 2019
The present article includes the enumeration of $n$-polygons with a certain symmetry property: For an even number $n$ of vertices, we count the $n$-polygons with $\frac{n}{2}$ symmetry axes. In addition, if $n$ is a power of 2, we show the relation to the perfect numbers.
