# Cantitruncated 5-cell

In four dimensional geometry, the cantitruncated 5-cell is a uniform polychoron. It is composed of 60 vertices, 120 edges, 80 faces, and 20 cells. The cells are: 5 truncated octahedra, 10 triangular prisms, and 5 truncated tetrahedra. Each vertex is surrounded by 2 truncated octahedra, one triangular prism, and one truncated tetrahedron.

Alternative names

* Cantitruncated pentachoron

* Cantitruncated 4-simplex

* Great prismatodispentachoron

* Truncated dispentachoron

* Grip (Jonathan Bowers: for great rhombated pentachoron)

The Cartesian coordinates of an origin-centered cantitruncated 5-cell having edge length 2 are:

These vertices can be more simply constructed on a hyperplane in 5-space, as the permutations of:

(0,0,1,2,3)

This construction is from the positive orthant facet of the cantitruncated pentacross.
