## Definition

A **Catalan polyhedron** is a dual polyhedron of an Archimedean polyhedron.

The vertices of the **Catalan polyhedra** are regular, and the faces are all congruent.

## Also known as

The **Catalan polyhedra** are also known as the **dual Archimedean polyhedra**.

Many sources refer to them as **Catalan solids**, but it is the general policy of $\mathsf{Pr} \infty \mathsf{fWiki}$ not to refer to polyhedra as **solids**, as this is technically a misnomer.
