Resumen:
We classify finite-dimensional complex pointed Hopf algebra withgroup of group-like elements isomorphic to $mathbb A_5$. We show that any pointed Hopf algebra with infinitesimal braiding associatedwith the conjugacy class of $pi in mathbb A_n$ is infinite-dimensionalif the order of $pi$ is odd except for $pi=(1 2 3)$ in $mathbb A_4$. We also study pointed Hopf algebras over the dihedral groups.
