Pentacontatetrapeton

The pentacontatetrapeton, or mo, also called the 122 polytope, is a convex noble uniform polypeton. It has 54 demipenteracts as facets, with 12 joining at a vertex forming a dodecateron as the vertex figure.

Vertex coordinates
The vertices of a pentacontatetrapeton of edge length 1, centered at the origin, are given by:
 * ($\sqrt{6}$/4, $\sqrt{3}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4) and all even sign changes
 * (±$\sqrt{2}$/2, ±$\sqrt{6}$//2, 0, 0, 0, 0) and all permutations in the first five coordinates
