On the partial $Π$ -property of second minimal or second maximal subgroups of Sylow subgroups of finite groups

Zhengtian Qiu, Jianjun Liu, Guiyun Chen

Let $H$ be a subgroup of a finite group $G$ . We say that $H$ satisfies the partial $Π$ -property in $G$ if if there exists a chief series $ \varGamma_{G}: 1 =G_{0} < G_{1}…

A New Characterization of Sporadic Groups

Zhongbi Wang, Heng Lv, Yanxiong Yan +1

Let $G$ be a finite group, $n$ a positive integer. $π (n)$ denotes the set of all prime divisors of $n$ and $π (G) = π (∣ G ∣)$ . The prime graph $Γ (G)$ of $G$ , defined by Grenberg and Keg…

On Normalized Table Algebras Generated by a Faithful Non-real Element of Degree 3-II

Zvi Arad, Guiyun Chen, Arisha Haj Ihia Hussam

The concept of "table algebra" was introduced by Z Arad anf H. Blau in order to study in a uniform way properties of products of conjugacy classes and of irreducible characters of…
