关于 C_(8,n,4) 和 C_(4n,8,2n) 的 K-优美性

ON THE K—GRACEFULNESS OF C8,n,4 AND C4n,8,2n

把由ｍ个ｎ回路Ｃｎ恰好有ｐ条相邻的公共边构成的图记为Ｃｎ，ｍ，ｐ，证明了图Ｃ８，ｎ，４和Ｃ４ｎ，８，２ｎ都是Ｋ—优美图。

In this paper, Cn,m,p denotes a graph that is composed by m loops Cn which has p common edges,and we prove that C8,n,4 and C4n,8,2n are both K—graceful.
