Abstract: Graphs $\Gamma$ with the following properties are classified: (i) $\Gamma$ is $(G,s)$-transitive for some $s \geqslant 4$ and some group $G \leqslant \operatorname {aut} (\Gamma )$ such that each vertex stabilizer in $G$ is finite, (ii) $s \geqslant (g - 1)/2$, where $g$ is the girth of $\Gamma$, and (ii) $\Gamma$ is connected. A new construction of ${J_3}$ is given.
