The **diretroprismatotetracontoctidisicositetrachoron**, or **dirpicdi**, 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 icositetrifaceted prismatoicositetritetracontoctachoron, but the great rhombihexahedra and triangular prisms are in different positions.

## Vertex coordinates[edit | edit source]

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