Small teritetradecapeton

The small teritetradecapeton or pentellated heptapeton, also called the pentellated 6-simplex, is a convex uniform polypeton. 2 hexatera, 10 pentachoric prisms, and 20 triangular-tetrahedral duoprisms join at each vertex. As the name suggests, it is the pentellation of the heptapeton. It can be constructed by expanding the facets of the heptapeton outward and filling in the gaps with new facets.
