The figure shown and described to the right and below is not a regular map. If we look for cycles of four faces, each bordering its two neighbours in the cycle, we find exactly three such cycles. The four remaining faces are not members of any such cycle.

Its Petrie polygons have 12 edges.



The figure shown and described to the right is also not a regular map.

Some of its Petrie polygons have four edges, some have six.
