[B]The Drive Completed on July 4, 2008
57 Primes Found
[/B]
Sieving stopped at 30T.
------------------------------------

In this drive, we'll search for k*2^n-1 primes for the following 14 k's < 300 divisible by 3:
51, 57, 117, 129, 135, 213, 237, 249, 261, 267, 273, 279, 285, 291.

The range of exponents is denoted by
n_min <= n <= n_max
where n_max=1M while n_min for respective Ks is given below.

k=213, n_min=250k
k=237, 249, 261, 273, 279, 291, n_min=260k
k=135, 267, n_min=300k
k=129, n_min=398k
k=57, n_min=400k
k=117, n_min=438k
k=285, n_min=470k
k=51, n_min=475k

With exception of k=129, for each k, n_min in the drive equals previously achieved n_max from our stats page. In case of k=129 we are leaving a 253-398k gap to be double-checked later. [It was most likely checked by Jeffrey who reported 5 primes, but there is no way to know because he hadn't reported the range he processed. Volunteers for double-checking are welcome.]

Sieving has been done by amphoria, Larry, Thomas, segmtfault, Battlemaxx, and me.
And recently by BlisteringSheep.

Happy hunting!

I completed k=213 in the 250-260 range, and found no primes. It was a kind of double-checking excercise because it was already reported primeless in this range by the "PrimeSearch" project, but we ["15k" at the time] tested all Ks around k=200-220 to 250k and I wanted to be certain.

All 9 Ks we are currently testing are completed to 350k now.
