0-2005G is reserved or done.
Ranges beyond that are free to use. Once you are done with the range, you can PM me and I can send you my email, to email me factors. Post reserved ranges below.

YOu have to open the zip file and change the pmin value, to start sieving from 2005G.

The command line I use is
srsieve -i 3_16data.txt -o 3_16data.txt -f 3_16factors.txt --pmax 2000000000000 --verbose

A range of 2T takes about a week.

The software I use is located

If you have any questions let me know.

I started this thread as an alternative method to searching for a prime bigger than 10 million digits. Once the n in 2^n-1 gets above a certain level(around 37-38 million, I think), then it becomes advantageous to look for a 10,000,000 digit prime around 33 million, using the expanded equation k*2^n-1.

I actually haven't ever participated in the search. I have an active imagination and sometimes, unpredictably, other people think my ideas make sense.

On the other hand, I'm sure there are people that I bug the crap out of. I'm never sure what effect my posts will cause.

I thought you were doing 0.04T-2T.

The range 2.005T and above is free, unless you reserved a range, that I am not aware of.
