Gosset 1 32 polytope

Gosset 1 32 polytope

In 7-dimensional geometry, 132 is a uniform polytope, constructed from the E7 group. It is named by Coxeter as 132 by its bifurcating Coxeter-Dynkin diagram, with a single ring on the end of the 2-node sequence. It is related to the 321 polytope, discovered by Thorold Gosset in 1900.

It is also one of a family of 127 (27 − 1) convex uniform polytopes in 7-dimensions, made of uniform polytope facets and vertex figures, defined by all permutations of rings in this Coxeter-Dynkin diagram::

This polytope can tessellate 7-dimensional space, with symbol 133, and Coxeter-Dynkin diagram::.
