The **icositetrachoric prism** or **icope** is a prismatic uniform polyteron that consists of 2 icositetrachora and 24 octahedral prisms. 1 icositetrachoron and 6 octahedral prisms join at each vertex. As the name suggests, it is a prism based on the icositetrachoron, which also makes it a convex segmentoteron.

The icositetrachoric prism contains the vertices of a regular penteract.

## Vertex coordinates[edit | edit source]

The vertices of an icositetrachoric prism of edge length 1 are given by all permutations and sign changes of the first four coordinates of:
