Polygram


Polygram

A regular polygram {n/k} is generalization of a (regular) polygon on n sides (i.e., an n-gon) obtained by connecting every ith vertex around a circle with every (i+k)th, "picking up" the pencil as needed to repeat the procedure after traversing the circle until none of the vertices remain unconnected.

Lachlan (1893) defines polygram to be a figure consisting of n straight lines.

The best-known polygrams are the pentagram and hexagram (a.k.a. Star of David). The following table summarizes some named polygrams.

n symbol polygram
5 5/2 pentagram
6 6/2 hexagram
7 7/2 heptagram
8 8/3 octagram
9 9/3 nonagram
10 10/3 decagram
