This paper completes the Wilf-classification problem for permutations avoiding a set of patterns in S4. Moreover, it completes finding an explicit formula for the generating function for the number permutations in Sn(T) for any subset T of S4, expect for only two cases T={1324} and T={3214,1324,2134}, as discussed in the introduction.
