On 8 October 2016, 21:01:14 UTC, PrimeGrid’s PRPNet found the largest known generalized Cullen prime:

682156*79^682156+1

The prime is 1,294,484 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 1st for generalized Generalized Cullen and Generalized Cullen-Woodall primes and 83rd overall.

The discovery was made by Franz-Xaver Harvanek (XAVER) of Austria using an Intel(R) Core(TM) i7-5960X CPU @ 3.00GHz with 32GB RAM, running Microsoft Windows 7 Ultimate. This computer took 3 hours and 44 minutes to complete the primality test using LLR.

For more details, please see the official announcement.

I find it ironic that shortly after the move of GCW from PRPnet to BOINC was announced that a prime was found.

Yeah, I got confused by that for a moment too, lol. Especially since we haven't seen one in quite a while.

Yes, I am well aware that GCW is still on PRPNet, that is why I found it ironic that a prime was found shortly after the move of GCW from PRPNet to BOINC was announced that a prime was found.
