Status of Factorization Efforts, 8,000 < n <= 9,000

For each composite number in this range, B.Kelly has done 422 runs of gmp-ecm (6.0) with B1=250,000. According to a table on the ECMNET web page, this should find most factors of 30 digits or less.

Each composite number in this range has been tested by A.Kruppa with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=1M and B2=100M.

Each composite number with less than 200 decimal digits in this range has been tested by A.Kruppa with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=1G and B2=1T.

Each composite number in this range have been tested by H.Bock with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=10M and B2=10G.

Each composite number with less than 800 decimal digits in this range have been tested by H.Bock with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=100M and B2=100G.
