Let D be a set of positive integers. The kappa value of D, denoted by \(\kappa (D)\), is the parameter involved in the so called “lonely runner conjecture.” Let xy be positive integers, we investigate the kappa values for the family of sets \(D =\{2, 3, x, y\}\). For a fixed positive integer \(x > 3\), the exact values of \(\kappa (D)\) are determined for \(y=x+i\), \(1 \le i \le 6\). These results lead to some asymptotic behavior of \(\kappa (D)\) for \(D=\{2, 3, x, y\}\).
