四度关系
四度关系-
本文考察了三度边正则图与四度Cayley图的关系，给出了一个由四度Cayley图构造三度边正则图的方法，并且构造了边正则图的三个无限族。
In this paper , we investigate the relations between cubic edge-regular graphs and Cayley graphs of degree 4 , and give a method to construct cubic edge-regular graphs by Cayley graphs of degree 4 . We construct three infinite families of cubic edge regular graphs .
