如果G△Aut(X),则称Cayley图 X = Cay(G ,S)是正规Cayley图。该文证明了,在同构意义下,所有A 6的连通5度非弧传递Cayley图中只有22个图是非正规Cayley图;最后,得到了A 6的连通5度非弧传递Cayley图的一个完全分类。
A graph X=Cay(G ,S) is called normal if G is normal in Aut(X ) .The paper proves that ,up to isomorphic ,there are twenty-two pentavalent connected Cayley graphs of A6 which are neither normal nor arc -transitive .At last ,the paper gets a complete classification of the pentavalent connected Cayley graphs of A6 .
