On $p$ -parts of conjugacy class sizes and the index of the $p$ -core

Yu Zeng, Jinbao Li, Yong Yang

For a prime $p$ and an arbitrary finite group $G$ , we show that if $p^{2}$ does not divide the size of each conjugacy class of \emph{ $p$ -regular} element (element of order not divi…

Proof of a conjecture of Green and Liebeck on codes in symmetric groups

Teng Fang, Jinbao Li

Let $A$ and $B$ be subsets of a finite group $G$ and $r$ a positive integer. If for every $g \in G$ , there are precisely $r$ pairs $(a, b) \in A \times B$ such that $g = ab$ , then $B$ is…

On some conjectures related to finite nonabelian simple groups

Jinbao Li, Wujie Shi

In this note we provide some counterexamples for the conjecture of Moretó on finite simple groups, which says that any finite simple group $G$ can determined in terms of its order…
