SQS-graphs of Solov'eva-Phelps codes
Italo J. Dejter
A binary extended 1-perfect code folds over its kernel via the Steiner quadruple systems associated with its codewords. The resulting folding, proposed as a graph inva…
On a -ultrahomogeneous oriented graph
Italo J. Dejter
The notion of a -ultrahomogeneous graph, due to Isaksen et al., is adapted for digraphs, and subsequently a strongly connected -ultrahomogeneous oriented gra…
Pappus-Desargues digraph confrontation
Italo J. Dejter
Like the Coxeter graph became reattached into the Klein graph in [2], the Levi graphs of the and self-dual configurations, known as the Pappus and Desargues (-trans…
Quasiperfect domination in triangular lattices
Italo J. Dejter
A vertex subset of a graph is a perfect (resp. quasiperfect) dominating set in if each vertex of is adjacent to only one vertex ( vert…
