Abstract Locally triangular graphs are known to be halved graphs of bipartite rectagraphs, which are connected triangle-free graphs in which every 2-arc lies in a unique quadrangle. A graph Γ is locally rank 3 if there exists G ⩽ Aut ( Γ ) such that for each vertex u , the permutation group induced by the vertex stabiliser G u on the neighbourhood Γ ( u ) is transitive of rank 3. One natural place to seek locally rank 3 graphs is among the locally triangular graphs, where every induced… Expand
