The retrofrustary prismatodishecatonicosachoron, or raffipady, is a nonconvex uniform polychoron that consists of 120 great rhombidodecahedra, 120 great dodecicosahedra, and 1200 hexagonal prisms. Two great rhombidodecahedra, two great dodecicosahedra, and four hexagonal prisms join at each vertex.

Vertex coordinates

Its vertices are the same as those of its regiment colonel, the antifrustary hexacositrishecatonicosachoron.
