Abstract
A simple undirected graph is said to be semisymmetric if it is regular and edge-transitive but not vertex-transitive. This paper gives a classificatio n of semisymmetric graphs of order 2pq where p and q are distinct primes. I t is shown that there are 143 examples of such graphs, 131 of which are bip rimitive.
