三、摘要

A graph is $G$-arc-transitive if it admits $G$ as a group of automorphisms acting transitively on the set of ordered pairs of adjacent vertices. A project completed recently was to classify $G$-arc-transitive graphs $\Gamma$ with $G$ imprimitive on the vertex set of $\Gamma$ such that the corresponding quotient graph is a complete graph and is almost multi-covered by $\Gamma$. In this talk we will discuss this classification together with related results.
