I'm at ~55K, one prime so far for low weight k: 1296*2020^52931-1

Almost at 60K, no new primes. VBCurtis, there are no candidates for k=1968 in sieve file, did you knock this k out?

I did, found two primes for it. I did not report here because the machine that found them overheated, and hasn't been booted up successfully since so I don't have specific n values.

12
138

R2020 primes for 1968: 46193 and 48526.

My desktop is functioning, but still runs hot. I'm slowly finishing to 50k on R2020. Likely another 4-6 days.

Two more primes for R2020:
Code:
419*2020^63826-1
776*2020^66346-1
I'll going to stop at n=70k.

R2020 finally made it to 50k on my end, 70k including unconnected's work.
Primes from 40k-50k:
1968 46193
1035 47247
1968 48526 (bummer, repeat)
There were 38 k's left at 40k. I took out two, while unconnected took out three. 33 k's remain at 70k.
Not continuing at present; I have a couple other loose ends to finish up on other projects before I continue this effort. The sieve file is a few posts up in this thread if anyone wants to take on a 5k or 10k block.

I'm stopped at n=70k, one more prime: 788*2020^67011-1

Whoops! "I'm going to stop" doesn't mean "I stopped". Whew, I'm glad you noticed my mistake, and also glad you found another prime!
