A heptapeton, or hepta-6-tope is a 6-simplex, a self-dual regular 6-polytope with 7 vertices, 21 edges, 35 triangle faces, 35 tetrahedral cells, 21 5-cell 4-faces, and 7 5-simplex 5-faces.

The name heptapeton is derived from hepta for seven facets in Greek and -peta for having five-dimensional facets, and -on.
