A '''Coxeter-Dynkin symbol''' is used to describe [[uniform polytopes]]. It consists of one or more separate and possibly branching chains of mirrors, which are either active ("x") or inactive ("o"), joined by lines with a given value. If no value is given for a particular line, its value is 3 by default. Coxeter-Dynkin symbols containing only one non-branching chain are described as being ''linear''. The status of the mirrors in linear symbols can also be written as a [[Dx number]]. | A '''Coxeter-Dynkin symbol''' is used to describe [[uniform polytopes]].

A Coxeter-Dynkin symbol is used to describe uniform polytopes. It consists of one or more separate and possibly branching chains of mirrors, which are either active ("x") or inactive ("o"), joined by lines with a given value. If no value is given for a particular line, its value is 3 by default. Coxeter-Dynkin symbols containing only one non-branching chain are described as being linear. The status of the mirrors in linear symbols can also be written as a Dx number.
