The **pentagonal duocomb** is a regular skew polyhedron found within four-dimensional Euclidean space. It can be formed as the comb product of two pentagons, or the from the extended Schläfli symbol . It has 25 square faces, 50 edges, and 25 vertices. It is a self-dual polyhedron.

## Vertex coordinates

Its vertex coordinates are the same as those of the pentagonal duoprism.
