Resumen:
Let pi in S_m be a product of disjoint cycles of the same length, C the conjugacy class of pi, and rho an irreducible representation of the centralizer of pi. We prove that either the Nichols algebra B (C, rho) is infinite dimensional or the braiding of the Yetter-Drinfeld module is negative.
