摘要

如果图Γ至少有一个2-弧且其自同构群在点集和2-弧集合上是传递的

则称该图为2-弧传递图.设G是基柱为交错群Ac(其中c≥5)的几乎单群

利用陪集图概念构造无平方因子阶的(G

2)-弧传递图.再通过分析自同构群和其点稳定子群的子群链结构

给出了该类图的分类.

Abstract

The graph Γ is said to be 2-arc-transitive if it has at least one 2-arc and Aut(Γ) is transitive on both the vertices and2-arcs of Γ. Let G be an almost simple group with soc(G) = Acfor c ≥ 5

we use the concept of coset graph to construct the graphs with square-free order and(G

2)-arc-transitive. Then by analyzing the subgroup chain structures between vertex-stabilizer subgroups and their automorphism groups

a classification of the(G

2)-arc transitive graphs of square-free order was given.
