Amazing finda huge congratulations for breaking the record for NPLB's biggest prime to date!
Also congrats to Batalov; one question though. I see that the prime was reported as having been found and proven with PFGW; is this an error, or are you actually using PFGW to search this? While there is no speed advantage to using one particular gwnumbased program over another for this kind of search, we do prefer that people use LLR for NPLB work so that the residues are compatible with future doublechecks. PFGW and Prime95 produce PRP residues, so they'll need to be doublechecked as such (which means needing to treat those separately from an otherwise straightforward doublecheck run).
