The authors study finite 2-groups with non-Dedekind non-metacyclic norm NGA of Abelian non-cyclic subgroups depending on the cyclicness or the non-cyclicness of the center of a group G. The norm NGA is defined as the intersection of the normalizers of Abelian non-cyclic subgroups of G. It is found out that such 2-groups are cyclic extensions of their norms of Abelian non-cyclic subgroups. Their structure is described.
