mersenneforum.org - The Second Megabit Drive

We are starting the second megabit drive, featuring Ks between 100 and 200, and initially we are going to test the following 19 Ks from n=1M to n=1.1M:

k = 115, 117, 123, 129, 135, 147, 149, 153, 155,
157, 159, 171, 173, 175, 179, 183, 185, 189, 193

When we reach 1.1M we might replace some Ks.
Please help yourself and happy hunting! :smile:

[B]Update (June 19, 2015):[/B] Extending the drive beyond n=2M and adding the following 11 Ks: 131, 133, 137, 139, 141, 143, 145, 161, 177, 181, and 187.

[B]Update (March 20th, 2020):[/B] Removing k=193 from the drive to be searched by an individual.

[B]Test Files[/B]
Extensively sieved by Psieve (the latest sieve file of July 31, 2011)

Attached is a file containing the list of candidates from n=2202k to 3000k. Note that it has not been broken into chunks so you will need to copy the first line into a file as well as the list of candidates you are searching.
