利用有限群的若干性质,分析了4pn阶素数度弧正则图的自同构群的结构,结合图的正规商图的性质,刻画了4pn阶的素数度弧正则图,并给出了n≤4时的完全分类.
By using some properties of finite groups, we analyze the structure of automorphism groups of arc - regular prime - valent graphs of order 4pn with p a prime. Then, applying certain properties of normal quotient graphs, we obtain a characterization of such graphs. In particular, a classification of such graphs is given for the case where n≤4.
