Let G be a finite group. The collection of all subgroups of G with maximal Chermak-Delgado measure is a sublattice of the subgroup lattice of G. This lattice was first introduced by Chermak and Delgado [A measuring argument for finite groups, Proc. Amer. Math. Soc., 107(1989), 907-914]. In the last years, there has been a growing interest in understanding this lattice, especially for finite p-groups. In this talk, we will introduce some recent works on this subject.
