N2 - A descending endomorphism of a group is an endomorphism that induces a corresponding endomorphism in every homomorphic image of the group. Descending endomorphisms of Abelian groups are power maps, and, in particular, those of finite Abelian groups as well as non-torsion Abelian groups are universal power endomorphisms. In this article, we compute all descending endomorphisms of some families of non-Abelian groups, namely (i) symmetric groups, (ii) direct products of symmetric groups, (iii) dihedral groups, (iv) direct products of dihedral groups, (v) Hamiltonian groups and (vi) dicyclic groups.
