摘要

我们讨论了一种新的三次图族,我们称之为群可分广义Petersen图(GDGP -图),它在定义和性质上与广义Petersen图族非常相似。本文的重点是确定图的代数性质,从我们的新族。我们寻找高度对称图,例如,具有大自同构群的图,以及顶点或弧传递图。特别地,我们给出了保证具有这些参数的图是顶点传递或Cayley的定义参数的算术条件,并且我们找到了一个既不是Feng和Wang的CQ图,也不是广义Petersen图的顶点传递GDGP -图。

A new generalization of generalized Petersen graphs
We discuss a new family of cubic graphs, which we call group divisible generalised Petersen graphs (GDGP -graphs), that bears a close resemblance to the family of generalised Petersen graphs, both in definition and properties. The focus of our paper is on determining the algebraic properties of graphs from our new family. We look for highly symmetric graphs, e.g., graphs with large automorphism groups, and vertexor arc-transitive graphs. In particular, we present arithmetic conditions for the defining parameters that guarantee that graphs with these parameters are vertex-transitive or Cayley, and we find one arctransitive GDGP -graph which is neither a CQ graph of Feng and Wang, nor a generalised Petersen graph.
