I planned to take R333 to n=250K and I've sieved it to ~40Т. Because of a lack of resources I haven't reserved it yet, so I can share this file if needed.

You can have it. I have plenty of others to work on. I haven't done anything with it. Have fun.

Riesel 320 complete to 50K. No primes found.
It took a little while longer than I expected, mainly because after a couple of tests, I found my CPU was at 100 degrees. After sorting that, it all ran fairly smoothly. I'll probably try and take this to 100K at some point, but not right now.

Good work G30ffr3y and thanks for the results. Hope to see you back again soon.

Thanks. So I take it to n=250K.

2258*361^41883-1
2520*361^36912-1
2622*361^28050-1
3314*361^60756-1

k=3314 is common with R19, so it helps two conjectures.

This has been a fruitful range.

You can add 4740*361^45551-1 and 6990*361^42853-1 to the mix. If I can find one more (between n=80000 and n=100000), then I can get this conjecture down to 5 remaining k.

There are now 7 k's remaining so you would need 2 more to make 5 remaining.

You are correct. I forgot that one had been taken to n=100000 already and is thus not being worked on by me.

S328 tested n=100K-200K - Nothing found

Results emailed - Base released

S256 done to 200K, and continuing to 300K. Currently around 232K (n<=1,859,752 in base 2)

/also prothsearch updated their search limits for k=831 to 1,300,000 - without a visible reservation, so some of my run was redundant/

That is due to work completed by PrimeGrid, although I see that Wilfrid hasn't updated http://www.prothsearch.net/rieselb.html since June.

That's ok, because those low values were fast to check anyway; it is only now that the progress starts to get a bit slower, -- at the ~2-million-bit size.
