Retroinverted prismatoicositetrachoron

The retroinverted prismatoicositetrachoron, or ripi, is a nonconvex uniform polychoron that consists of 24 quasirhombicuboctahedra and 96 triangular prisms. Four quasirhombicuboctahedra and four triangular prisms join at each vertex.

It can be constructed as the blend of 3 qrit, with the oct cells blending out.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great distetracontoctachoron.
