    Heawood graph
    Percy John Heawood (1861-1955) was an English mathematician who spent a large amount of time on questions related to the four colour theorem. . It is the point-line incidence graph of the Fano plane, and is commonly called the Heawood graph. It occurs as subgraph of the Hoffman-Singleton graph It is the unique (3,6)- cage : the regular cubic graph of girth 6 with minimal number of vertices. co-Heawood graph . It occurs as subgraph of the Gewirtz graph
    Group
    The full group of automorphisms is PGL(2,7) = L (2).2, acting distance-transitively with point stabilizer S
    Subgraphs
    Substructures belonging to the maximal subgroups of the automorphism group: a) A partition of the edges into three matchings . There are 8 of these, forming a single orbit. The stabilizer of one is 7:6, with vertex orbit size 14. (There are 24 matchings. The complement of a matching is a 14-cycle that decomposes unique into two matchings. So, matchings come in groups of three.) b) A vertex . There are 14 of these, forming a single orbit. The stabilizer of one is S , with vertex orbit sizes 1+3+6+4.

    A Critical Eye
    • Kempe was unable to solve the problems brought up by Heawood.
    • Heawood further investigated the problem, and gave us the Heawood Estimate, for the necessary number, in terms of the Euler characteristic of the surface. P. G. Tait - Further
      contributed to the Theorem. Percy Heawood - Refuted
      all of Kempe’s proof.
