Both a graph and its complement are self-centered with identical radius

Malaravan, A. Chellaram; Baskar, A. Wilson (Işık University Press, 2021)

We show that a graph and its complement are self-centered with identical radius r only when r = 2. Further, we provide a construction of such a graph for any given order at least eight.
