The small dodecahemidodecahedral prism or sidhiddip, is a prismatic uniform polychoron that consists of 2 small dodecahemidodecahedra, 12 pentagonal prisms, and 6 decagonal prisms. Each vertex joins 1 small dodecahemidodecahedron, 2 pentagonal prisms, and 2 decagonal prisms. As the name suggests, it is a prism based on the small dodecahemidodecahedron.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the icosidodecahedral prism.
