I created a table which summarizes testing status for all Proth candidates ever tested on planned to test on PrimeGrid (K=5...9999, N=0...10M). You can find it here:

http://boincvm.proxyma.ru:30080/test4vm/public/pps_dc_status.php

The table also shows questionable areas (tested on PrpNet or in Adaptive Replication mode) which do contain invalid results and must be partially or fully double-checked to be sure that no primes were missed. The doublechecking is currently running in "LLR2 testing" subproject on "Private GFN server" (the link above).

For what it's worth, PPS-DIV tested k=19683 from n=300K to n=4M. Below that, I tested everything myself and JimB did the same; we only checked that the lists of primes matched. (And this was in 2019, so no Gerbicz check/LLR2. But it's a very small amount of work anyway.)

Egad! That is a large number of tests that need double-checking.

Fortunately most of that double-checking should be quick, but I suspect there is no active project to do that double-check.

Just saw the news about Pavel Atnashev's prime! Congrats!

https://primes.utm.edu/primes/page.php?id=133721

Very exciting to find one missed as a result of adaptive replication. Probably the first of many with the smaller n values coming up soon.

I wonder how many will be found, and I wonder how many of those will be large enough for T5K.

Yes, this is excellent news!

I already corrected the OEIS entry A053357.

The new Proth prime is a factor of xGF(2051864, 7, 3) = 7^(2^2051864) + 3^(2^2051864). And note that Atnashev's name already shows up one additional time on http://www.prothsearch.com/GFNfacs.html because of this (you can search the page for 2051864).

Great find. Congratulations!

It seems that (7^(2^m) + 3^(2^m))/2 is prime only for m equal to 0, 1, or 8. The last one is somewhat nice, (7^256 + 3^256)/2 (with 217 digits).

Can you explain what is adaptive replication?

Many years ago PrimeGrid would not double check work from hosts that were deemed to be reputable enough.
