Decayotton

A decayotton, or deca-9-tope is a 9-simplex, a self-dual regular 9-polytope with 10 vertices, 45 edges, 120 triangle faces, 210 tetrahedral cells, 252 5-cell 4-faces, 210 5-simplex 5-faces, 120 6-simplex 6-faces, 45 7-simplex 7-faces, and 10 8-simplex 8-faces.

The name "decayotton" is derived from "deca" for ten facets in Greek and -yott (variation of oct for eight), having 8-dimensional facets, and "-on".
