The prismatorhombated tesseract, or prit, also commonly called the runcitruncated 16cell, is a convex uniform polychoron that consists of 24 cubes, 32 hexagonal prisms, 16 truncated tetrahedra, and 8 small rhombicuboctahedra. 1 cube, 2 hexagonal prisms, 1 truncated tetrahedron, and 1 small rhombicuboctahedron join at each vertex. As one of its names suggests, it can be obtained by runcitruncating the hexadecachoron.

Representations[edit  edit source]
A prismatorhombated tesseract has the following Coxeter diagrams:
 x4o3x3x () (full symmetry)
 xxxxxx4ooxxoo3xuxxux&#xt (B_{3} axial, small rhombicuboctahedronfirst)
 qo3xx3oq *b3xx&#zx (D_{4} symmetry)
 Xwx xxx4oox3xux&#zx (B_{3}×A_{1} symmetry)
Semiuniform variant[edit  edit source]
The prismatorhombated tesseract has a semiuniform variant of the form x4o3y3z that maintains its full symmetry. This variant uses 8 small rhombicuboctahedra of form x4o3y, 16 truncated tetrahedra of form z3y3o, 24 square prisms of form z x4o, and 32 ditrigonal prisms of form x y3z as cells, with 3 edge lengths.
With edges of length a, b, and c (such that it forms a4o3b3c), its circumradius is given by .
It has coordinates given by all permutations of:
 .

The prismatorhombated tesseract is the colonel of a 3member regiment that also includes the small cubihexadecadisoctachoron and the small rhombiprismic disoctachoron.
The great rhombicuboctahedral prism can be obtained as the central segment of the prismatorhombated tesseract in small rhombicuboctahedronfirst orientation.
