The small rhombidodecahedral prism or sirdip is a prismatic uniform polychoron that consists of 2 small rhombidodecahedra, 30 cubes, and 12 decagonal prisms. Each vertex joins 1 small rhombidodecahedron, 2 cubes, and 2 decagonal prisms. As the name suggests, it is a prism based on the small rhombidodecahedron.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the small rhombicosidodecahedral prism.
