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 icositetrachoron of 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).

Representations
A rectified icositetrachoron has the following Coxeter diagrams:


 * o3x4o3o (full symmetry)
 * o4x3o3x (BC4 symetry, small rhombated hexadecachoron)
 * x3o3x *b3x (D4 symetry, as prismatorhombated demitesseract)
 * s4x3o3x (as snub)
 * ooqoo4xxoxx3oxxxo&#xt *BC3 axial, cuboctahedron-first)
 * xoxuxox4oqoooqo3ooqoqoo&#xt (BC3 axial, cube-first)
 * xo4oq3oo3qo&#zx (BC4 symmetry, rectified dual ico)
 * qqo3ooo3qoq *b3oqq&#zx (D4 symmetry)
 * Qqo oqq4xxo3oxx&#zx (BC3×A1 symmetry)

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Cuboctahedron (24): Icositetrachoron
 * Cube (24): Icositetrachoron
 * Square (144): Semi-uniform small prismatotetracontoctachoron
 * Triangle (96): Rectified icositetrachoron
 * Edge (288): Small rhombated icositetrachoron
