Great icosicosidodecahedral prism

The great icosicosidodecahedral prism or giidip is a prismatic uniform polychoron that consists of 2 great icosicosidodecahedra, 12 pentagonal prisms, 20 triangular prisms, and 20 hexagonal prisms. Each vertex joins 1 great icosicosidodecahedron, 1 pentagonal prism, 1 triangular prism, and 2 hexagonal prisms. As the name suggests, it is a prism based on the great icosicosidodecahedron.

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