It varies from 0 for trees to 1 for maximal planar graphs.
For instance, a well-covered 3-connected maximal planar graph may be obtained via the clique cover construction from any 3t-vertex maximal planar graph in which there are t disjoint triangle faces by adding t new vertices, one within each of these faces.
blocks of strangulated graphs: the strangulated graphs are exactly the graphs that can be formed as clique-sums of complete graphs and maximal planar graphs.
The maximal planar graphs without separating triangles that may be formed by repeated splits of this type are sometimes called blocks,
the strangulated graphs are the graphs that can be formed by clique-sums of cliques and maximal planar graphs without deleting edges.
Apollonian networks are examples of maximal planar graphs, graphs to which no additional edges can be added without destroying planarity,
Every chordal graph can be decomposed in this way into a clique-sum of complete graphs, and every maximal planar graph can be decomposed into a clique-sum of 4-vertex-connected maximal planar graphs.
In a maximal planar graph, or more generally in every polyhedral graph,
it is the graph of a simplicial polyhedron if it is a maximal planar graph.
are exactly the clique-sums of cliques and maximal planar graphs, again without edge deletions.
Any maximal planar graph may be decomposed into 4-vertex-connected maximal planar subgraphs by splitting it along its separating triangles(triangles that are not faces of the graph):
A maximal planar graph is node-pancyclic if and only if it has a Hamiltonian cycle:
However, unlike planar graphs(for which all maximal planar graphs on a given vertex set have the same number of edges as each other),
by a given maximal planar graph and set of Euclidean
An Apollonian network is a maximal planar graph in which all of the blocks are isomorphic to the complete graph K4.
As with every maximal planar graph, it is also 3-vertex-connected: the removal of any two of its vertices leaves a connected subgraph.
Koebe-Andreev-Thurston theorem: If G is a finite maximal planar graph, then the circle packing whose tangency graph is isomorphic to G is unique,
The Goldner-Harary graph provides an example of a planar graph that does not have book thickness two: it is a maximal planar graph, so it is not possible to add any edges to it while preserving planarity, and it does not have a Hamiltonian cycle.
For a graph that is already maximal planar it is possible to show a stronger construction of a simple cycle separator,
However, there are infinitely many 3-connected well-covered maximal planar graphs.
