Opis: We give a new proof that there exists a unique strongly regular graph with parameters (81, 20, 1, 6). Unlike the finite geometry approach used by Brouwerand haemers, we use linear algebra and spectral graph theory concepts, namely the technique of star complements, in our proof.Ključne besede: graph theoryObjavljeno v RUP: 15.10.2013; Ogledov: 2748; Prenosov: 32 Povezava na celotno besedilo
