Paley-type graphs of order a product of two distinct primes

In this paper, we initiate the study of Paley-type graphs \(\Gamma_N\) modulo \(N=pq\), where \(p,q\) are distinct primes of the form \(4k+1\). It is shown that \(\Gamma_N\) is an edge-regular, symmetric, Eulerian and Hamiltonian graph. Also, the vertex connectivity, edge connectivity, diameter and...
