Finite groups with the most Chermak-Delgado measures of subgroups

Guojie Liu, Haipeng Qu, Lijian An

Let $G$ be a finite group and $H \leq G$ . The Chermak-Delgado measure of $H$ is defined as the number $∣ H ∣ \cdot ∣ C_{G} (H) ∣$ . In this paper, we identify finite groups that exhibit the…

Finite p-groups with at most p2 + p subgroups not in Chermak-Delgado lattice

Guojie Liu, Haipeng Qu, Lijian An

The Chermak-Delgado lattice of a finite group G is a self-dual sublattice of the subgroup lattice of G. In this paper, we determine finite p-groups with at most p2 + p subgroups no…
