Ayyy, first T5k prime. My second prime overall and my first one was a Sophie-Germain prime on Primegrid. :bounce:

[QUOTE=Luminescence;601087]... was a Sophie-Germain prime on Primegrid. :bounce:[/QUOTE]
The correct term is "a prime that was a byproduct in the SG search project". It was not [URL="https://mathworld.wolfram.com/SophieGermainPrime.html"]a Sophie-Germain prime[/URL]. The paired value was not prime.

Semantics.

A HUGE congrats on your first prime and what an extraordinary one it is!

It is the largest prime ever found by NPLB by almost 600,000 digits!! It enters the top-5000 list ranked #303!

I take it by your ID and search effort that 333 is your lucky number. :smile:

I also "found" the known prime 435*2^1853363-1 which is already listed in T5k

Max found:
889*2^1715909-1 is prime

321*2^2946654-1 is prime!

My first top-5000 prime on this drive. :smile:

They come in pairs...

303*2^2949403-1 is prime!

My 1st prime is Top 5000 :) :) :)
