Octaexon

An octexon, or octa-7-tope is a 7-simplex, a self-dual regular 7-polytope with 8 vertices, 28 edges, 56 triangle faces, 70 tetrahedral cells, 56 5-cell 5-faces, 28 5-simplex 6-faces, and 8 6-simplex 7-faces.

The name "octaexon" is derived from "octa" for eight facets in Greek and "-ex" for having six-dimensional facets, and "-on".
