That makes around 7,7 months for one of those sequences; if using two servers. However without a deeper sieve file i wont start working on them. A sieve up to P = 1e15 should erase around 500 or 600 canidates.

It is still a lot of work regardless, but i think i can handle it. ^^

R6 tested to n = 5.4e6. Residues attached. Testing continues.

[rebirther]

Reserving S30 to n=1M (800k-1M) for BOINC

[rebirther]

Reserving R25 to n=300k (150-300k) for BOINC --> all available k by sievefile

[rebirther]

R25 tested to n=300k (150-300k)

9 primes found, 108 remain

Results emailed - Base released

[rebirther]

S30 tested to n=1M (800k-1M)

nothing found, 2 remain

Results emailed - Base released

[rebirther]

Reserving R7 to n=100k (25-100k) (200-300M) for BOINC

[rebirther]

S9 tested to n=5M (2-5M)

nothing found, 1 remain

Results emailed - Base released

s19 tested till n=191k

New primes:

441244*19^190791+1

Working on a large base like R7 is troublesome, but i still decided to give it some effort.

And after a few days i have results. The range 408034000000 up to 408034255081 is proven.

The last k just fell a few hours ago.

408034056294*7^226772-1 is prime! (191657 decimal digits, P = 3)  Time : 342.596 sec.

The results and primes can be found in results_max_range_R7.zip. The files created from srbsieve will be added in a few minutes. (Edit: added now)



I am reserving the range >408G for testing up to n=25K. [5400 k´s remaining at n=3350; quickly decreasing]

You should have reserved it first. I would have stated the following:

This is too messy to show on the pages. Sorry.

I suggest working your way upwards from k>500M (lowest untested) on the k's for this huge-conjectured base. Starting at the end and working backwards makes for too much admin work.
