The icositetrifaceted prismatoicositetritetracontoctachoron, or ifpic, is a nonconvex uniform polychoron that consists of 48 octahedra, 24 quasitruncated hexahedra, 24 great rhombihexahedra, and 96 triangular prisms. Two octahedra, four quasitruncated hexahedra, four great rhombihexahedra, and four triangular prisms join at each vertex.

It has the same cell counts as the diretroprismatotetracontoctodisicositetrachoron, but the small rhombihexahedra and triangular prisms are in different positions.

Vertex coordinates

Its vertices are the same as those of its regiment colonel, the great distetracontoctachoron.
