The Gray graph is a unit-distance graph
Leah Berman, Gábor Gévay, Tomaž Pisanski
Izvirni znanstveni članek
Oznake: polycirculant;unit-distance graph;Gray graph;ADAM graph;generalized Petersen graph;
In this note we give a construction proving that the Gray graph, which is the smallestcubic semisymmetric graph, is a unit-distance graph.

Polycyclic geometric realizations of the Gray configuration
Leah Berman, Gábor Gévay, Tomaž Pisanski

The Gray configuration is a (27_3) configuration which typically is realized as the points and lines of the 3×3×3 integer lattice. It occurs as a member of an infinite family of configurations defined by Bouwer in 1972. Since their discovery, both the Gray configuration and its Levi graph (i.e., its ...

Symmetries of the Woolly Hat graphs
Leah Berman, Sergio Hiroki Koike Quintanar, Elías Mochán, Alejandra Ramos Rivera, Primož Šparl, Stephen Wilson
Izvirni znanstveni članek
Oznake: edge-transitive;vertex-transitive;tricirculant;Woolly Hat graphs;
A graph is edge-transitive if the natural action of its automorphism group on its edge set is transitive. An automorphism of a graph is semiregular if all of the orbits of the subgroup generated by this automorphism have the same length. While the tetravalent edge-transitive graphs admitting a semir ...
