Relations to other Regular Maps

Its dual is the Dyck map.

Its Petrie dual is N22.4.

It can be 2-fold covered to give S5:{3,8}.
It is a 2-fold cover of S2:{3,8}.

It can be 2-split to give R21.16.
It can be 5-split to give R75.7′.

It can be rectified to give the quasi-Dyck map.

It can be obtained by triambulating S3:{6,4}.

It can be stellated (with path <1,-1>) to give S3:{4,8|4} . The density of the stellation is 3.

Underlying Graph

Its skeleton is K4,4,4.


This regular map features in Jarke J. van Wijk's movie Symmetric Tiling of Closed Surfaces: Visualization of Regular Maps, 1:30 seconds from the start. It is shown as a "wireframe diagram", on K4. The wireframe is arranged as the skeleton of the tetrahedron.
