The paper classifies factorizations of almost simple groups where at least one factor is solvable. It then applies this classification to characterize s-arc-transitive Cayley graphs of solvable groups, discovering that, except for cycles, all non-bipartite connected 3-arc-transitive Cayley graphs are covers of the Petersen or Hoffman-Singleton graphs.

The paper presents a specialized study in group theory and graph theory, offering a classification of factorizations and characterization of Cayley graphs. While mathematically rigorous, its impact is primarily confined to the theoretical realm. The paper lacks broader implications and does not present significant methodological innovation, thus warranting an average rating.
