The First Megabit Drive
The First Megabit Drive
I am pleased to announce our first multik drive featuring only megabit exponents.
Initially we have the following 6 Ks sieved up to p=54T.
k = 51, 57, 61, 65, 69, 87
We have more Ks being sieved right now. They will be added later, either as a part of this drive, or in a new drive.
Happy hunting!
Note (Jan. 26 2011): k = 47, 53 added as Batch2
Note2 (Aug. 12, 2014): k=51 and 69 removed from the drive,
The following Ks added:
k=35, n > 2520k
k=37, n > 2500k, only n !=1 mod 10
k=103, n >= 2550223
k=111, n >= 2601487
As the results, the following 10 Ks are now being tested: 35, 37, 47, 53, 57, 61, 65, 87, 103, and 111.
