Generalized Cullen and Woodall factors found in the period 2007 January 1 - March 31 Only factors >= p20 are given explictly here. The 2000q4 table lists the finders of smaller factors and their tally of such. Under Method, ECM is the elliptic curve method; MPQS is the multiple polynomial quadratic sieve; SIQS is the self-initializing version of MPQS; SNFS is the special number field sieve; GNFS is the general number field sieve; P-1 is Pollard's P-1 factoring algorithm, P+1 is William's P+1 algorithm and "alg" denotes an algebraic factorization.
