Great icosahedral prism

The great icosahedral prism or gipe is a prismatic uniform polychoron that consists of 2 great icosahedra and 20 triangular prisms. Each vertex joins 1 great icosahedron and 5 triangular prisms. As the name suggests, it is a prism based on the great icosahedron.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small stellated dodecahedral prism.
