Small retrofrustary prismatotetracontoctitetrisicositetrachoron

The small retrofrustary prismatotetracontoctitetrisicositetrachoron, or sirfpacuti, is a nonconvex uniform polychoron that consists of 48 cuboctahedra, 24 great rhombihexahedra], 24 [[quasirhombicuboctahedron|quasirhombicuboctahedra, 24 small cubicuboctahedra, 24 cuboctatruncated cuboctahedra, and 96 hexagonal prisms. Two cuboctahedra, two great rhombihexahedra, two quasirhombicuboctahedra, two small cubicuboctahedra, four cuboctatruncated cuboctahedra, and four hexagonal prisms join at each vertex.

It has the same cell counts as the great retrofrustary prismatotetracontoctitetrisicositetrachoron, but the great rhombihexahedra, quasirhombicuboctahedra, and small cubicuboctahedra are in different positions.

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