The face shares all its vertices and edges with itself. Some readers
may consider that this invalidates it as a regular map.
The figure shown and described here is not a regular map. Some vertices are connected to three distinct vertices, others are connected to only two, one of them twice.
This map has one 18-gonal face, six vertices, and nine edges.
Its dual is {3,18}.
