Gracefulness of Two Kinds of M-quadrangular Cactus
Xu Yun · 2007
LIU Chun-feng and others have proved the K-gracefulness and sequential features of M-quadrangular cactus of both A Type and B Type.In this paper,we provide another graceful labeling(also k-gracefulness labeling),with which we can prove that the two M-quadrangular cactus are alternating graphs with odd gracefulness and equilibrium.
