Prime-magic labelings of \(K_{n,n}\) (Q2639076)

This paper deals with so-called prime-magic labelings of the complete bipartite \(K_{n,n}\), \(n\geq 4\). After having shown that the minimal value which can be assigned to the prime-magic graph \(K_{4,4}\) is 114, the authors give examples of prime-magic labelings of \(K_{n,n}\), \(n=5,6,7\), and formulate a conjecture referring to the minimal value which can be assigned to \(K_{n,n}\), \(n\geq 5\).
