We classify finite-dimensional complex pointed Hopf algebras with group of group-like elements isomorphic to . We show that any pointed Hopf algebra with infinitesimal braiding associated with the conjugacy class of is infinite-dimensional if the order of is odd except for in . We also study pointed Hopf algebras over the dihedral groups.
