543-560 completed, reserving 560-600.

77743*6^560745-1 is prime! (50809.5367s+0.0516s)
This is my largest prime and 2nd largest CRUS prime :smile:

AMAZING!!

Congrats Dmitry! :smile: I cannot believe how fast the k's are dropping on this base. This is worthy of a few dancing George's:

:george::george::george::george::george:

Only 3 k's to go!

Congratulations, Dmitry - you and Serge have really taken this search to where an end to the tunnel is within imagination! Good luck on the next one!

Congratulations on an amazing prime! :shock: I must admit, I'm rather surprised this one came as soon as it did, continuing what would seem to be an extremely "lucky" streak. Hopefully the rest will fall similarly! :smile:

Congrats That was a realy nice one :smile:

Great find, Dima! Congratulations and let's go bananas!
:maybeso::maybeso::maybeso::maybeso::anurag::banana::banana::banana:

I have posted an updated sieve file with k=77743 removed. There are now only 3 k's remaining and only 2 k's remaining to be searched for n=600K-1M.

Because we have found so many primes and k=77743 was the highest weight k of the 4 that were previously remaining, no more sieving will be needed up to n=1M. Also, there are now only 3058 candidates remaining to be tested up to n=750K. So...let's put a push on to move this drive towards n=750K over the next few months.

If the interest is still here once we push past n=750K, I'll start a sieving drive for n=1M-2M for the remaining 3 k's. We can then discuss if we want to continue the team drive or if people would like to reserve individual k's for testing.

Thanks all for congratulations! I do my best and here is another probable prime.

43994*6^569498-1 is a probable prime! Wd1: 4BF6C3BE,00000000
Need to check with pfgw.

I'm very lucky with Riesel base 6, so I take remaining k=36772 to 750k.

:flex::flex::flex: Awesome work! :toot::toot::toot:
