Gosset 2 41 polytope

Gosset 2 41 polytope

In 8-dimensional geometry, 241 is a uniform polytope, constructed from the E8 group. It is named by Coxeter as 241 by its bifurcating Coxeter-Dynkin diagram, with a single ring on the end of the 2-node sequence. It is related to the 421 polytope, discovered by Thorold Gosset in 1900.

It is also one of a family of 255 (28 − 1) convex uniform polytopes in 8-dimensions, made of uniform polytope facets and vertex figures, defined by all permutations of rings in this Coxeter-Dynkin diagram: :
