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 for eight, having 8-dimensional facets, and -on.
