[edit] Geometry

In general, an octagram is any self-intersecting octagon (8-sided polygon).

The regular octagram is labeled by the Schläfli symbol {8/3}, which means an 8-sided star, connected by every 3rd point.

There is one compound star figure, {8/2}, composed of two squares, called the Star of Lakshmi.
