The great rhombidodecahedral prism or girdip is a prismatic uniform polychoron that consists of 2 great rhombidodecahedra, 30 cubes, and 12 decagrammic prisms. Each vertex joins 1 great rhombidodecahedron, 2 cubes, and 2 decagrammic prisms. As the name suggests, it is a prism based on the great rhombidodecahedron.

Vertex coordinates[edit | edit source]

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