Rectified icositetrachoron

The rectified icositetrachoron, or rico, also commonly called the rectified 24-cell, is a convex uniform polychoron that consists of 24 cubes and 24 cuboctahedra. Two cube and three cuboctahedra join at each triangular prismatic vertex. As the name suggests, it can be obtained by rectifying the icositetrachoron.

It can also be constructed as the cantellated hexadecachoron, under BC4 symmetry. This is due to the fact the regular icositetrachoron coincides with the rectified hexadecachoron.

Vertex coordinates
The vertices of a rectified icositetrachoronof edge length 1 are given by all permutations of:
 * (±$\sqrt{2}$, ±$\sqrt{3}$/2, ±$\sqrt{2}$/2, 0).

The rectification of the dual icositetrachoron has vertices given by:


 * (±3/2, ±1/2, ±1/2, ±1/2),
 * (±1, ±1, ±1, 0).
