Characterizing Finite Groups via Subgroup Perfect Codes

Binbin Li, Jingjian Li, Wei Meng +1

A perfect code in a graph $Γ = (V, E)$ is a subset $C$ of $V$ such that no two vertices in $C$ are adjacent and every vertex in $V ∖ C$ is adjacent to exactly one vertex in…

Symmetric graphs of prime valency with a transitive simple group

Jing Jian Li, Zai Ping Lu

A graph $\Ga=(V,E)$ is called a Cayley graph of some group $T$ if the automorphism group $\Aut(\Ga)$ contains a subgroup $T$ which acts on regularly on $V$ . If the subgroup $T$ is…
