Quick update on k=146921775.

Found 6 more primes for n=50k-100k, so in total 102 primes for n=0-100k.

Now working from n=1.29M up.

Can I reserve 6371?
No primes in Caldwell's base.
Interesting that its twin 6373 has prime.
Can somebody explain, why so many Proth primes for k=6371?
Pre-thanks.

You may. It has primes at n = 38, 182,374,430. See rieselprime.de, menu "riesel data".
Someone checked it (and all k < 10,000) to n=10000 years ago to seed those web pages.

Status for k>300 I've been testing:
2055 and 2085 are complete to 1025k, which I believe is the point where they joined one of the megabit drives. There had been a gap in the 607-620k range. I am not testing these, but was previously doing so in the under-1M range years ago, so I filled the gap when I discovered it.
2115 is complete to 1.56M.
2145 complete to 1.36M.
2175 complete to 1.33M.
All 5 of these had a gap from 607k to 620k, and filling that gap produced one prime (posted in the small primes thread, 2115@607390).
405 is complete to 1.72M.
443 is complete to 3.31M.

k = 17849 has reached n = 1M. Primes and residues were posted to the "Post small primes..." thread.
I am releasing this k, and reserving k = 17851.
