Abstract: Let $ \Gamma $ be a finite connected undirected graph, $ G$ a vertex-transitive subgroup of $ \operatorname{aut} (\Gamma )$, $ \{ x,y\} $ an edge of $ \Gamma $ and $ {G_i}(x,y)$ the subgroup of $ G$ fixing every vertex at a distance of at most $ i$ from $ x$ or $ y$. We show that if the stabilizer $ {G_x}$ contains a normal subgroup inducing $ {L_3}(p)$, $ p$ a prime, on the set of vertices adjacent to $ x$, then $ {G_5}(x,y) = 1$.
