Abstract

Let G be a finite abelian group such that G ≠ {0} and a, bG \ {0}. Let CG(a, b) be the graph whose vertex set is G and the edge set is given by
E = {{x, x + a}, {x, x + b}, {x, x − a}, {x, x − b} : xG}.
In this work, we use the properties of finite abelian group to derive isomorphism testing on the graph CG(a, b) defined above. We study classes of isomorphic graphs. This work generalizes Nicoloso and Pietropaoli’s paper ⟦2⟧.
