Status of Factorization Efforts, 4,000 < n <= 5,000

For each composite number in this range, B.Kelly has done 500 runs of gmp-ecm with B1=250,000. According to the gmp-ecm documentation, this should find most factors of 30 digits or less.

For each composite number in this range, N.Daminelli has done 165 runs of gmp-ecm with B1=1M.

For each composite number less than or equal to 530 decimal digits, H.Bock has done 2753 runs of gmp-ecm with B1=3M.

Each composite number in this range has been tested by N.Daminelli with the gmp-ecm implemenation of Pollard's p-1 algorithm with B1=250M and B2=6T.

Each composite number in this range has been tested by H.Bock with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=1G and B2=1P.

Each composite number with less than or equal to 550 decimal digits in this range has been tested by H.Bock with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=10G and B2=36P.

Each composite number in this range has been tested by N.Daminelli with the gmp-ecm implemenation of Pollard's p+1 algorithm with B1=50M and B2=756G.

Each composite number with less than or equal to 540 decimal digits in this range has been tested by H.Bock with the gmp-ecm implementation of the p+1 algorithm with B1=2G and B2=5P and with option -x0 23/11.

Each composite number with less than or equal to 418 decimal digits in this range has been tested by H.Bock with the gmp-ecm implementation of the p+1 algorithm with B1=10G and B2=10P and with option -x0 23/11.
