7115634*7^273464-1
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
