Primes of the form 2401*2^n+1
I'm planning on searching k=2401 up to 3 million. I have a feeling that this base is slightly lucky due to 2401 = 7*7*7*7.

I realized that PrimeGrid is already doing all the k's from 1 to 10000 so k=2401 is already taken. Maybe I'll do k = 1234321 instead?

For open k's,you can take a look here
 https://pzktupel.de/Primetables/TableProthTOP10KK.php Line 3446 is listed a k=2401. This top-10000 starts with numbers >308000 digits. Last fiddled with by Cybertronic on 2023-05-13 at 16:28 |
