摘要
本文给出由基回数为2的自中心图添加一条链而得到的基回数为3,直径不变的自中心图的全部类型。从而把[2]中的结论推广到一般情况。
In this paper,we provide all kinds of the self- Centered graphs with cyclomaic number 3,which are made by added a chain to a self-centered graph with cyclomaic number2, and their diameters are the same to the predecessor。Then some propositions in [2]is extended to general case.
