Through duality, these graphs correspond to the 257 convex octahedra with eight
faces enumerated by Kirkman (1862-1863) and Hermes (1899ab,
1900, 1901), as documented by Federico (1969) and Duijvestijn and Federico (1981).
Britton and Dunitz (1973) catalogue convex polyhedra
by vertex count up to eight vertices.
The name "octahedral graph" is also used for this class (Gayathri 2018, p. 50). It is distinguished here from the six-vertexoctahedral graph, the skeleton
of the regular octahedron.
