List of regular maps in orientable genus 3.
Its skeleton is cubic Klein graph.
This regular map, embedded in 3space, can be bought from shapeways, in the form seen to the right (click on the image for a larger version). It is not so clear from a photograph how this physical object portrays the Klein map; if you have one in your hands where you can use binocular vision on it, it works better. This model was designed and uploaded to shapeways by Henry Segerman.
This and its dual are the smallest regular maps to reach the Hurwitz limit B97, which states that the number of edges of a regular map cannot exceed 21 × the Euler characteristic of the surface.
This regular map features in Jarke J. van Wijk's movie Symmetric Tiling of Closed Surfaces: Visualization of Regular Maps, 1:40 seconds from the start. It is shown as a "wireframe diagram", on K_{4}. The wireframe is arranged as the skeleton of
