Thanks for the heads-up. Occasionally my internet service provider changes the number of my IP address. This happens rarely but without notice and since I access chesswanks.com locally I usually don't notice until someone complains. When it happens I have to go to DYNDNS and have the domain point to the new number, which I have now done.

I have examined all Leyland numbers in the gap between L(147999,10) <148000> and L(148999,10) <149000> and found 11 new primes.

I have examined all Leyland numbers in the four gaps between L(222748,3) <106278>, #1986, and L(45405,286) <111532> and found 80 new primes. That makes L(45405,286) #2070.

That was interval #17. Interval #18 still has a month of sieving before I can even get a start on it. I'll be doing intervals #21, #25, and #26 until then.
