|James Robertson graph|
The Robertson graph is Hamiltonian.
|Named after||Neil Robertson|
The Robertson graph is also a Hamiltonian graph which possesses 5,376 distinct directed Hamiltonian cycles.
The Robertson graph is not a vertex-transitive graph and its full automorphism group is isomorphic to the dihedral group of order 24, the group of symmetries of a regular dodecagon, including both rotations and reflections.
The characteristic polynomial of the Robertson graph is
