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…

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…

On a {K_4,K_{2,2,2}}-ultrahomogeneous graph

Italo J. Dejter

The existence of a connected 12-regular ${K_{4}, K_{2, 2, 2}}$ -ultrahomogeneous graph $G$ is established, (i.e. each isomorphism between two copies of $K_{4}$ or $K_{2, 2, 2}$ in $G$ exte…
