Summary

[edit]
Description
bipartite version

The Heawood graph is the Levi graph of the Fano plane.
The black vertices denote vertices of the Fano plane, and the white vertices denote edges of the Fano plane.
E.g. vertex 3 is part of the circular edge (3, 5, 6), the diagonal edge (4, 7, 3), and the side edge (1, 3, 2).

Fano plane
The black vertices form the 7-cycle of a permutation
