This paper forms part of a study of 2-arc transitivity for finite imprimitive symmetric graphs, namely for graphs admitting an automorphism group G that is transitive on ordered pairs of adjacent vertices, and leaves invariant a nontrivial vertex partition B. Such a groupG is also transitive on the ordered pairs of adjacent vertices of the quotient graph B corresponding toB. If in additionG is transitive on the 2-arcs of (that is, on vertex triples ( , , ) such that , and , are adjacent and… CONTINUE READING
