Abstract:Let D(m, n; k) be the semi-direct product of two finite cyclic groups $${\mathbb{Z}/m=\langle x\rangle}$$ and $${\mathbb{Z}/n=\langle y\rangle}$$ , where the action is given by yxy −1  =  x k . In particular, this includes the dihedral groups D 2m . We calculate the automorphism group Aut (D(m, n; k)).
