The quasidisprismatodishecatonicosachoron, or quadippady, is a nonconvex fissary uniform polychoron that consists of 120 regular dodecahedra, 120 great stellated dodecahedra, 720 pentagonal prisms, and 720 pentagrammic prisms. 4 dodecahedra, 4 great stellated dodecahedra, 12 pentagonal prisms, and 12 pentagrammic prisms join at each vertex. It is the result of pushing the cells of either a grand hecatonicosachoron or a great stellated hecatonicosachoron inwards.
It is fissary as vertices coincide by four, producing a compound vertex figure; in addition, edges coincide by two.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the ditetrahedronary dishecatonicosachoron.
