Small retrointercepted ditetrahedronary prismatodishecatonicosachoron

The small retrointercepted ditetrahedronary prismatodishecatonicosachoron, or sarned tippady, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 720 pentagonal prisms, and 120 small rhombidodecahedra. Four ditrigonary dodecadodecahedra, twelve pentagonal prisms, and twelve small rhombidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small ditetrahedronary hexacosihecatonicosachoron.
