High Quality Content by WIKIPEDIA articles! In geometry, an octagram is an eight-sided star polygon. A star polygon is a non-convex polygon which looks in some way like a star. Only the regular ones have been studied in any depth; star polygons in general appear not to have been formally defined. They should not be confused with star domains. In general, an octagram is any self-intersecting octagon (8-sided polygon). The regular octagram is labeled by the Schlafli 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.
