It was me. It was after I found this lovely pair:

Code:

591*2^530223-1  Mini-Geek
565*2^530221-1  Mini-Geek

I don't recall precisely what I found, but I remember pulling data from primes beside NPLB. Looking back at the files from that, it looks like at much lower n values there were pairs in the same n (261255 and 217588, if I'm reading my old file correctly). I haven't done new analysis, but I'd assume Karsten's post above mine is correct for all Drive 1 primes.

921*2^589470-1 is prime! Time : 459.0 sec.

When I submitted it, I saw this for the fist time.
(Unverified because Untested)
Does that mean it's a new one?

(It's Prime Day, Kman1293 also found one)

Whew! Awesome prime day!

It just means that the top-5000 site hasn't tested it for primality yet. It's been verified now.

If the prime had previously been submitted, it wouldn't have gotten that far so yes, that also means it's a new one.
