论文摘要
给定一个有限的$ g $，我们用$ l（g）$表示$ g $的子组晶格，$ {\ cal cd}（g）$ Chermak-delgado lattice $ g $。在本说明中，我们确定有限的$ g $，以便$ | {\ cal cd}（g）| = | l（g）| -k $，$ k = 1,2 $。
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 $|{\cal CD}(G)|=|L(G)|-k$, $k=1,2$.
