具有大Chermak-Delgado格的有限群
Finite groups with large Chermak-Delgado lattices
摘要：
给定一个有限群$G$，我们用$L(G)$表示$G$的子群格，用${\cal CD}(G)$表示$G$的Chermak-Delgado格。本文确定了有限群$G$使得$|{\cal CD}(G)|=|L(G)|-k$，$k=1,2$ .
英文摘要：
Given a finite group $G$, we denote by $L(G)$ the subgroup lattice of $G$ and by ${\cal CD}(G)$ the Chermak-Delgado lattice of $G$. In this note, we determine the finite groups $G$ such that $|{\cal CD}(G)|=|L(G)|-k$, $k=1,2$.
