R base 31 is tested to n=120k and paused. Sieve file to n=150k.
R base 30 is tested to n=110k and paused. Sieve file to n=140k.

I'll keep hold of these for a bit unless someone else wants them.

(I've been distracted by twin primes again ... )

Sierp base 31 is at n=23K; 38 primes found for n=22K-23K. 1162 k's remain. Continuing...

Base 10 (Riesel + Sierpinski) checked till n=360000. I'm still working on it.

Releasing Riesel base 24 at n=50K. 20 primes so far (all verified, 8 new since my update at 40K), 110 k's remaining.
Primes from 40K-50K:

Code:

16724*24^40540-1
3714*24^42202-1
6001*24^43557-1
20122*24^43906-1
27309*24^44876-1
9329*24^46632-1
8266*24^48233-1
18504*24^48462-1

Sierp Base 12 tested to n=500K.

Nothing found. Continuing

For my prime Riesel conjecture project I found:
26099*28^94180-1

just short of the top 5000.

Sierp base 31 is at n=24K; 28 primes found for n=23K-24K. 1134 k's remain.

Now on the downhill stretch towards n=25K. I'll be glad when this is done.

Base=10 (Sierpinski + Riesel) tested till n=373500, I am releasing k=8579 due to recent prime (8579*10^373260-1), which eliminates ~43,81% of candidates from the input file

I am still working on remaining k: 4421 (Riesel), 7019 (Riesel), 7666 (Sierpinski).

R base 31 is unreserved at n=120202. Next test is at n=120205; no gap.
Sieve to n=150k (3.5T) and results attached.

R base 30 to follow when I access other PC.

Chris,

Is the correct sieve depth for your sieve file P=3.5T? If so, I'll change the header line in the file to reflect that.

Thanks for providing your file.
