A space-filling tridecahedron[1][2] is a tridecahedron that can completely fill three-dimensional space without leaving gaps. It has 13 faces, 30 edges, and 19 vertices. Among the thirteen faces, there are six trapezoids, six pentagons and one regular hexagon.[3]

The dual polyhedron of the space-filling tridecahedron

The polyhedron's dual polyhedron is a enneadecahedron. It is similar to a twisted half-cube, but one of its vertices is treated as a face before twisting.
