I haven't seen any PrimeGrid announcement yet, but 3752948*2^3752948-1 is prime!

In fact it is a prime Geoff, but it seems that there is some mistake in the proof code, because at least Multisieve aswell as GCWSieve should have been mentioned unless mr. Thompson has found a different way to search for Woodalls :)

Happy New Year!

It's roughly in the same range as PrimeGrid's search...maybe it was really a PrimeGrid prime but it was misreported? I don't know why anyone would be foolish enough to try searching for Cullens or Woodalls on their own, especially that close to the PrimeGrid range...they'd be bound to get steamrolled by PrimeGrid before long.
