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.
