The small ditetragonal spinoduoprism, or sidtindip, is a nonconvex uniform polychoron that consists of 32 tetrahedra, 64 triangular prisms, 64 cubes, and 16 small rhombihexahedra. One tetrahedron, three triangular prisms, four cubes, and three small rhombihexahedra join at each vertex.
It is the blend of 2 sidpith and 2 snipto.
It was discovered on March 2, 2006 by Jonathan Bowers following Mason Green's discovery of ondip and gondip.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the octagonal spinoduoprism.
