%X We compute the Betti numbers for all the powers of initial and final lexsegment edge ideals. For the powers of the edge ideal of an anti¨Cd path, we prove that they have linear quotients and we characterize the normally torsion¨Cfree ideals. We determine a class of non¨Csquarefree ideals, arising from some particular graphs, which are normally torsion¨Cfree.
