Abstract
In this note we prove that the Chermak–Delgado lattice of a ZM-group is a chain of length 0, more precisely \({\mathcal {CD}}(\mathrm{ZM}(m,n,r))=\{H_{(1,d,0)}\}\), where d is the multiplicative order of r modulo m. A similar conclusion is obtained for all dihedral groups \(D_{2m}\) with \(m\ne 4\).
