Spectra and the exact number of Automorphisms of Paley-type graphs of order a product of n distinct primes
Paley graphs are Cayley graphs which are circulant and strongly regular. Paley-type graph of order a product of two distinct Pythagorean primes was introduced by Dr Angsuman Das. In this paper, we extend the study of Paley-type graphs to the order a product of n distinct Pythagorean primes. We have determined its adjacency spectra and the exact number of the automorphisms.
