Tetrahedron atop triangular cupola

Tetrahedron atop triangular cupola, or tetatricu, is a CRF segmentochoron (designated K-4.24 on Richard Klitzing's list). As the name suggests, it consists of a tetrahedron and a triangular cupola as bases, connected by 1 tetrahedron, 1 triangular cupola and 6 triangular prisms.

It can be formed by diminishing a tetrahedral cupola by a triangular cupofastegium.
