graphscope.nx.generators.small.heawood_graph(create_using=None)

Returns the Heawood Graph, a (3,6) cage.

The Heawood Graph is an undirected graph with 14 nodes and 21 edges, named after Percy John Heawood [1]. It is cubic symmetric, nonplanar, Hamiltonian, and can be represented in LCF notation as [5,-5]^7 [2]. It is the unique (3,6)-cage: the regular cubic graph of girth 6 with minimal number of vertices [3].

Parameters:

create_using (NetworkX graph constructor, optional (default=nx.Graph)) – Graph type to create. If graph instance, then cleared before populated.

Returns:

G – Heawood Graph with 14 nodes and 21 edges

Return type:

networkx Graph
