This genus-3 regular map, shown to the right, has two octagonal faces, each meeting four times at each of its two vertices. It has eight edges, and a Euler characteristic of -4.

Its Petrie polygons have two edges, and its holes have four edges.

It is self-dual.
It is a double cover of S^{2}:{8,8}.
Its Petrie dual is the 8-hosohedron.
It can be cantellated to produce S^{3}:{8,4}.

Its rotational symmetry group is C8×C2.

Each face shares all its vertices with itself. Some readers may consider that this invalidates it as a regular map.

Each face is antipodal to the other; each vertex is antipodal to the other; the eight edges form a single antipodal set. Rotating one edge about its centre causes every other edge to remain where it is and rotate about its centre: this is the central involution of its rotational symmetry group.
