摘要
对于可以由一个内卷和一个奇素数元素生成的群 G,本文给出了一个充分条件,即 G 的某个 Cayley 图是一个图形正则表达式(GRR),也就是 Cayley 图具有与 G 同构的全自形群。
Graphical regular representations of (2,p)-generated groups
For groups that can be generated by an involution and an element of odd prime order, this paper gives a sufficient condition for a certain Cayley graph of to be a graphical regular representation (GRR), that is, for the Cayley graph to have full automorphism group isomorphic to . This condition enables one to show the existence of GRRs of prescribed valency for a large class of groups, and in this paper, -valent GRRs of finite nonabelian simple groups with are considered.
期刊介绍:
The European Journal of Combinatorics is a high standard, international, bimonthly journal of pure mathematics, specializing in theories arising from combinatorial problems. The journal is primarily open to papers dealing with mathematical structures within combinatorics and/or establishing direct links between combinatorics and other branches of mathematics and the theories of computing. The journal includes full-length research papers on important topics.
