The quasitruncated cuboctahedral prism, or quitcope, is a prismatic uniform polychoron that consists of 2 quasitruncated cuboctahedra, 6 octagrammic prisms, 8 hexagonal prisms, and 12 cubes. Each vertex joins one of each type of cell. As the name suggests, it is a prism based on the quasitruncated cuboctahedron.

The quasitruncated cuboctahedral prism can be vertex-inscribed into the great cubihexadecadisoctachoron.

Vertex coordinates

The vertices of a quasitruncated cuboctahedral prism of edge length 1 are given by all permutations of the first three coordinates of:

• $\left(±\frac{2\sqrt2-1}{2},\,±\frac{\sqrt2-1}{2},\,±\frac12,\,±\frac12\right).$
