The small retrofrustary prismatodisicositetrachoron, or sirfipdi, is a nonconvex uniform polychoron that consists of 24 quasirhombicuboctahedra, 24 small rhombicuboctahedra, and 96 hexagonal prisms. Two quasirhombicuboctahedra, two small rhombicuboctahedra, and four hexagonal prisms join at each vertex.
It has the same cell counts as the great retrofrustary prismatodisicositetrachoron, but the quasirhombicuboctahedra and small rhombicuboctahedra are in different positions.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the antifrustary distetracontoctachoron.
