Finite p-groups with at most p2 + p subgroups not in Chermak-Delgado lattice
arXiv:2307.13946
Abstract
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 not in Chermak-Delgado lattice.
