Properties convex

In geometry, the rectified 24-cell is a uniform 4-dimensional polytope (or uniform polychoron), which is bounded by 48 cells: 24 cubes, and 24 cuboctahedra.

It can also be considered a cantellated 16-cell with the lower symmetries B4 = [3,3,4], or even D4. B4 would lead to a bicoloring of the cuboctahedral cells into 8 + 16 colors, and D4 leads to 3 colors, 8 of each.
