SQS-graphs of Solov'eva-Phelps codes

Italo J. Dejter

A binary extended 1-perfect code $C$ folds over its kernel via the Steiner quadruple systems associated with its codewords. The resulting folding, proposed as a graph inva…

Pappus-Desargues digraph confrontation

Italo J. Dejter

Like the Coxeter graph became reattached into the Klein graph in [2], the Levi graphs of the $9_{3}$ and $1 0_{3}$ self-dual configurations, known as the Pappus and Desargues ( $k$ -trans…

Quasiperfect domination in triangular lattices

Italo J. Dejter

A vertex subset $S$ of a graph $G$ is a perfect (resp. quasiperfect) dominating set in $G$ if each vertex $v$ of $G ∖ S$ is adjacent to only one vertex ( $d_{v} \in {1, 2}$ vert…
