k=157 has struck again! :w00t:

157*2^869073-1 is prime!

(Edit: Whoops, posted this in the wrong thread. Can someone please move it to the k<300 thread? Thanks. :smile:)

This is the right thread. You are the only one who posts primes in k<300, so you got it right this time.
We post reservations and updates there, and primes in the "post primes here" thread. Logical?

Oh, okay. I always thought you were supposed to post everything related to k<300, both primes and reservations/statuses, in the k<300 thread. But, you're right, it does make more sense to post all the primes here. :smile:

In that case, then, could a mod please move my post about my earlier k=157 prime to this thread? (It's currently in the k<300 thread.) :smile:

1121*2^19678-1 is prime!
1121*2^46130-1 is prime!
1121*2^153466-1 is prime!

424163685*2^437804 - 1 is prime! [131801 digits]
