Great retroinvertifrustary prismatotetracontoctitetrisicositetrachoron

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

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

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