Query: On pointed Hopf algebras associated with the symmetric groups II   This is a sequel to arXiv:0807.2406. It is shown that the Nichols algebras
over the symmetric groups S_m, m > 4, are all infinite-dimensional, except
(maybe) those related to the transpositions considered by Fomin and Kirillov,
resp. Milinski and Schneider, and the class of type (2,3) in S_5.
