关于最单群${\rm {\bf PGL(2,9)}}$的素图不可识别性

On The Unrecognizability by Prime Graph for the Most Simple Group ${\rm {\bf PGL(2,9)}}$

Ali Mahmoudifar

摘要:

有限群$G$的素图记为$\ga(G)$。又称$G$是素图可识别的当且仅当每个具有$\ga(H)=\ga(G)$的有限群$H$同构于$G$ .本文将所有具有相同素图的有限群分类为$\textrm{PGL}(2,9)$。特别地,我们给出了一些与$\textrm{PGL}(2,9)$具有相同素图的可解群。

英文摘要:

The prime graph of a finite group $G$ is denoted by $\ga(G)$. Also $G$ is called recognizable by prime graph if and only if each finite group $H$ with $\ga(H)=\ga(G)$, is isomorphic to $G$. In this paper, we classify all finite groups with the same prime graph as $\textrm{PGL}(2,9)$. In particular, we present some solvable groups with the same prime graph as $\textrm{PGL}(2,9)$.
