The swirlprismatic diacositetracontitetracosioctacontachoron, or spiddit, is a nonconvex uniform polychoron that consists of 240 pentagonal prisms and 480 pentagrammic prisms. Twenty pentagonal prisms and forty pentagrammic prisms join at each vertex.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the small stellated hecatonicosachoron.
