8354966*7^288802-1
9871172*7^367701-1
I will extend the range up to n=500K. Considering to go for a new and better sieved sieve file after passing n=400K.
Please post the primes for k<=2M.

Please give the test depth for k=2M-10M.

I can't update the statuses on the pages without both primes and test depths.

Thanks!

k<2M found no additional primes; only that one from a while ago.
k=2M-10M is now at n=368K.

R15 reached n=50K, found 41 primes. (this work only took about 1,5 months; but ehh problems.)
Anyway in the range 10M-20M are now 45 k´s remaining and running towards n=100K.



Results attached.

R7 k<2M is now tested up to n=1000000 with no other primes found. Releasing this range.

R7 k=700M-800M reached n=25K. 2063 k´s are remaining in this range; releasing this range.


Results can be found here


Range 800M-900M is at 19,2k and 900M-1G is at 17,6K.




Range 2M-10M is now at n=399k (a few more to pass 400K), found two primes since last update


Code:
4780002*7^368053-1 is prime! (311048 decimal digits, P = 3)  Time : 700.341 sec. (shortly after the update!)
5333174*7^380887-1 is prime! (321894 decimal digits, P = 5)  Time : 726.703 sec

I will do a new sieve file soon, hoping it will speed things up

R7, k-range 800M-900M reached n=25K; results are here. 2108 k´s remaining in that range.
R7, k-range 900M-1e9 reached n=25K, results are here. 2075 k´s remaining in that range.


Releasing both ranges. I doubt the effort for 1e9 up to 2e9 is worth at this moment, so i will focus on other things.


R7, k-range 2M-10M is now at 442K with two new primes. Target is still n=500K but i dont think I can reach that until the years end.



Code:
3885264*7^419940-1 is prime! (354898 decimal digits, P = 3)  Time : 917.120 sec.
9012942*7^425310-1 is prime! (359436 decimal digits, P = 3)  Time : 932.953 sec.
Funny how they appear so close sometimes, see 9871172*7^367701-1 and 4780002*7^368053-1. The prime before them was at 280K.

s19 tested till n=193k

New primes:
Code:
499936*19^191388+1
397276*19^191568+1
369054*19^191817+1
353986*19^192248+1
683974*19^193073+1
However, I stopped working on this, because it got too heavy for me alone.

Please let me know, if you need any files, so others can continue this base.

How many tests are left?
