Status of Factorization Efforts, 9,000 < n < 10,000

For each composite number in this range, N.Daminelli and H.Bock have done 422 runs of gmp-ecm with B1=250,000 According to the gmp-ecm documentation, this should find most factors of 30 digits or less.

N.Daminelli has completed 990 runs of gmp-ecm with B1=1M for the Aurifeuillan composites in this range.

N.Daminelli has completed 60 runs of gmp-ecm with B1=1M for the composites in this range.

Each composite number with less than 436 decimal digits in this range has been tested by N.Daminelli with 990 runs of gmp-ecm with B1=1M.

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=500M and B2=200T.

Each composite number with less than or equal to 1501 decimal digits 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 600 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=20P.

Each composite number with less than or equal to 350 decimal digits in this range has been tested by H.Bock with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=100G and B2=500P.

Each composite number in this range has been tested by N.Daminelli with the gmp-ecm implementation of the p+1 algorithm with B1=6M and B2=93G.

Each composite number in this range with less than 1000 decimal digits has been tested by H.Bock with the gmp-ecm implementation of the p+1 algorithm with B1=100M and B2=6T.

Each composite number in this range with less than or equal to 350 decimal digits has been tested by H.Bock with the gmp-ecm implementation of the p+1 algorithm with B1=2G and B2=5P.
