Let S be a subset of the cyclic group Zn. The cyclic Haar graph H(Zn, S) is the bipartite graph with color classes Zn + and Zn − , and edges {x + , y − }, where x, y ∈ Zn and y − x ∈ S. In this paper we give sufficient and necessary conditions for the isomorphism of two connected cyclic Haar graphs of valency 4.
