The great dodecahemicosahedral prism or gidhipe, is a prismatic uniform polychoron that consists of 2 great dodecahemicosahedra, 12 pentagonal prisms, and 10 hexagonal prisms. Each vertex joins 1 great dodecahemicosahedron, 2 pentagonal prisms, and 2 hexagonal prisms. As the name suggests, it is a prism based on the great dodecahemicosahedron.

Vertex coordinates[edit | edit source]

Its vertices are the same as those of its regiment colonel, the dodecadodecahedral prism.
