1 22 polytope

[1] Its Coxeter symbol is 122, describing its bifurcating Coxeter-Dynkin diagram, with a single ring on the end of the 1-node sequence.

Seen in a configuration matrix, the element counts can be derived by mirror removal and ratios of Coxeter group orders.

[5] Vertices are colored by their multiplicity in this projection, in progressive order: red, orange, yellow.

Its construction is based on the E6 group and information can be extracted from the ringed Coxeter-Dynkin diagram representing this polytope: .
