چکیده

The notion of a C-ultrahomogeneous graph, due to Isaksen et al., is adapted for digraphs, and then a strongly connected ~ C4-ultrahomogeneous oriented graph on 168 vertices and 126 pairwise arc-disjoint 4-cycles is presented, with regular indegree and outdegree 3 and no circuits of lengths 2 and 3, by altering a definition of the Coxeter graph via pencils of ordered lines of the Fano plane in which pencils are replaced by ordered pencils.

On C-ultrahomogeneous graphs and digraphs

The notion of a C-ultrahomogeneous graph, due to Isaksen et al., is adapted for digraphs and studied for the twelve cubic distance transitive graphs, with C formed by g-cycles and (k − 1)-paths, where g = girth and k = arc-transitivity. Excluding the Petersen, Heawood and Foster (90 vertices) graphs, one can go further by considering the (k− 1)-powers of g-cycles under orientation assignments p...

Orienting and separating distance-transitive graphs

It is shown that exactly 7 distance-transitive cubic graphs among the existing 12 possess a particular ultrahomogeneous property with respect to oriented cycles realizing the girth that allows the construction of a related Cayley digraph with similar ultrahomogeneous properties in which those oriented cycles appear minimally ”pulled apart”, or ”separated” and whose description is truly beautifu...

From the Coxeter Graph to the Klein Graph

We show that the 56-vertex Klein cubic graph Γ′ can be obtained from the 28-vertex Coxeter cubic graph Γ by ’zipping’ adequately the squares of the 24 7-cycles of Γ endowed with an orientation obtained by considering Γ as a C-ultrahomogeneous digraph, where C is the collection formed by both the oriented 7-cycles ~ C7 and the 2-arcs ~ P3 that tightly fasten those ~ C7 in Γ. In the process, it i...

On K*-Ultrahomogeneous Graphs

Let C be any class of graphs. A graph G is C-ultrahomogeneous if every isomorphism between induced subgraphs belonging to C extends to an automorphism of G. We study graphs that are K∗-ultrahomogeneous, where K∗ is the class of complete graphs. We also explicitly classify the graphs that are tK∗-ultrahomogeneous, where tK∗ is the class of disjoint unions of complete graphs.

Pappus-Desargues digraph confrontation

Like the Coxeter graph became reattached into the Klein graph in [3], the Levi graphs of the 93 and 103 self-dual configurations, known as the Pappus and Desargues (k-transitive) graphs P and D (where k = 3), also admit reattachments of the distance-(k − 1) graphs of half of their oriented shortest cycles via orientation assignments on their common (k−1)-arcs, concurrent for P and opposite for ...
