In general, a heptagram is any self-intersecting heptagon (7-sided polygon ). There are two regular heptagrams, labeled as {7/2} and {7/3}, with the second number representing the vertex interval step from a regular heptagon, {7/1}. This is the smallest star polygon that can be drawn in two forms, as irreducible fractions.
The hieratic signs stood for fractions of a hekat, the basic Egyptian measure of volume.
