Pentacontahexahecatonicosihexaexon

The pentacontahexahecatonicosahexaexon, or lin, also called the 132 polytope, is a convex uniform polyexon. It has 56 pentacontatetrapeta and 126 demihexeracts as facets, with 7 of each at a vertex forming a birectified heptapeton as the vertex figure.

The pentacontahexahecatonicosihexaexon contains the vertices of a birectified hexacontatetrapetal prism.

Vertex coordinates
The vertices of a pentacontahexahecatonicosihexaexon of edge length 1, centered at the origin, are given by:
 * ($\sqrt{7}$/4, $\sqrt{3}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, ±1) and all even sign changes of the first 6 coordinates
 * (±$\sqrt{2}$/2, ±$\sqrt{2}$/2, ±$\sqrt{2}$/2, 0, 0, –0, ±1/2) and all permutations of first 6 coordinates
 * (3$\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, 0) and all even sign changes and all permutations of the first 6 coordinates

Representations
A pentacontahexahecatonicosihexaexon has the following Coxeter diagrams:
