A run at n=590K takes around 1050 secs. A run at around 780K takes around 3500 secs. 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. ^^

Small range of R7 proven
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. Code:
408034056294*7^2267721 is prime! (191657 decimal digits, P = 3) Time : 342.596 sec. I am reserving the range >408G for testing up to n=25K. [5400 k´s remaining at n=3350; quickly decreasing] Last fiddled with by MisterBitcoin on 20210112 at 18:41
