After mining PrimeGrid data, I have pulled together the remaining n < 500000 for some of the k.

Reserving 310K-320K (2825 candidates)

KEP · 2013-11-24, 20:27

n=310K-320K is complete. 2825 results completed. Nothing found.

KEP · 2014-02-17, 16:17

It appears that k=727 for S2 is tested to n=2M, wich makes k=2908 for S16 tested to n=500K, unfortunantly Primegrid found no primes we could use or the rieselprime.de site should seriously be updated

Technically we only have 20 k's remaining in this drive. By monday or maybe as early as sunday, I'll start my RS383 reservation, wich will last about 4 months. If no one has completed this drive by the time I complete my RS383 reservation, I'm going to reserve the entire range from n=320K to n=500K for the 20 k's remaining.

The 20 k's is "only" a 47604 tests, if no further primes are found, so who is up for the challenge?

Take care

Kenneth

Ps. Forgot to mention that all other k's is either b2 k>10000 and therefor not officially searched by anyone for n=>1 and for those k's that transforms to b2 k<10000 the testdepth is below current testdepth of n=320K for S16, so the conclusion is that only k=2908 is able to be removed from the drive, while the rest needs to stay

I'd like to leave k=2908 in there for double checking. It's not a lot of extra work.

Reserving n=320K-500K for the remaining 21 k's. I'll start processing the remaining candidates by friday. ETA ~18 weeks (maybe more). I'm going to report status every 3-4 weeks.

Take care

S16 is at n=330K. Nothing new found. Continuing happily!

Next n=10K increase should come sooner than this one, since there is no delaying challenge for any of the conjectures that Primegrid is working on

Kenneth!

S16 is completed to n=340K, with a leading edge of n=342K

and

47395*16^340281+1 is prime.

20 k's remain in the drive. Overall if this is the start of a prime-shower similar to the prime-shower for S16 for the n=200K-300K range, we will soon see more long suistainable primes entering the Top-5000 list and furthermore we will see S16 go below 20 k's remaining.

Take care

Kenneth
