Abstract: A long-lasting open question in the literature of strategic network formation is the characterization of nonminimal Nash networks in the context of two way flow model with nonrival information. In this note, I provide a partial answer to this question for the class of nonminimal networks such that every chain between two agents has the length of at most two and heterogeneity in information value possessed by each agent is assumed. I show that every strict Nash network is a strongly nested split graph. I also show that every strict Nash network is also efficient given a specific structure of information value.
