Abstract:An infinite class of new binary linear completely transitive (and so, completely regular) codes is given. The covering radius of these codes is growing with the length of the code. In particular, for any integer ρ≥2, there exist two codes in the constructed class with d=3, covering radius ρ and lengths View the MathML source and View the MathML source, respectively. The corresponding distance-transitive graphs, which can be defined as coset graphs of these completely transitive codes are described.
Keywords:Completely regular code  Completely transitive code  Covering radius  Distance-regular graph  Distance-transitive graph  Intersection numbers  Outer distance  Uniformly packed code
