摘要:
潘江敏教授等人在文章[Arc-transitive Cayley graphs on non-ableian simple groups with soluble vertex stabilizers and valency seven, arXiv:1707.09785v1, 2017]中构造了交错群A62上的一个7度弧传递非正规Cayley图。在本文中,我们将证明该图的全自同构群同构于A63。
Abstract:
Pan et al. in [Arc-transitive Cayley graphs on non-ableian simple groups with soluble vertex stabi-lizers and valency seven, arXiv:1707.09785v1, 2017] constructed an example of a nonnormal arc-transitive 7-valent Cayley graph on the alternating group A62. In this paper, we will prove that the full automorphism group of this graph is isomorphic to A63.
