The pseudorhombic prismatopentachoron, or pirpop, is a nonconvex uniform polychoron that consists of 5 truncated tetrahedra, 10 triangular prisms, and 10 hexagonal prisms. 2 truncated tetrahedra, 2 triangular prisms and 4 hexagonal prisms join at each vertex.

Vertex coordinates[edit | edit source]

Its vertices are the same as those of its regiment colonel, the small rhombated pentachoron.
