Default update on k=93

k=93 has been sieved until 440bn for 330000<n<400000 and 3600 tests are left.
I hope (expect! ) that I will find at least 1 prime in this range, for I am searching a long long time on a new one.

After a couple of big primes for my ks < 300, I thought I'd post a status
update for all of them:

69: Complete through n=580k, prime at n=580596
231: Complete through n=750k, prime at n=749301
247: Complete through n=850k

All 3 are continuing

This is just a status update:

k=29: tested upto n=1.6M

No new primes found, continuing both k.

I'll take k=191 a little bit further. The stats page reports that it is tested upto n=270000, so I'll start there. Please let me know, if someone else is already testing this k.

Thomas, thanks for your report, I updated the stats page, and reserved k=191 for you. I'm not aware that anybody else is working on it.

BTW, I cancelled outstandig reservations by Jeffrey of k=9, 51, 59, and 117. It's possible that he checked these k's to a little bit higher limits than indicated but I have no means to find out. I think he stopped all his clients shortly after he found a prime for k=9 at n=828k.
