The Riesel record for 127 had a very short life:

R 21013492486553 66 125/17542
R 21013492486553 66 126/18270
R 21013492486553 66 127/18954
R 21013492486553 66 128/19034

Off to Egypt now for 2 weeks so no chance any of my computers' batteries will survive the 7 times a day power cuts here in Dhaka.

Back from Egypt..needed that break.

Decided to concentrate on a second batch of Riesels taking them up to 100K. I have one great performer, with two new absolute records (133,134) (and counting), the second of which is a 10% improvement. Also broke a number of Riesel records

I will take this quickly up to 100000

Need 135/30353 or less for the Riesel record or 135/26925 or less for the absolute

Congrats on this new record breaker, Robert!

I've temporarily stopped all instances of payam.exe in favor of pfgw testing a bunch of quite promising candidates.
The current testing limits for the Sierpinski side are given below.
So, this is the chance for others to [B]join the search![/B]
For newcomers I wouldn't suggest to go beyond E=106, since for the higher ones finding just one VPS typically takes a few days...

Still advancing this candidate through the 8 times a day power cuts. The candidate fell a bit behind on 140-144 but

There is still another bunch of about 130 sequences waiting at n=50k for which I'll try to get at least the best performers to n=100k.

Crikey, this can't fail to beat the best...only 3 more prps in the next 200000n needed. p/ln(n) >14 is a real landmark. Never before achieved. I wonder what the Nash weight is?

I am almost there with getting my second batch to 30K, but it is uphill battle against 12 hour power cuts a day. Even at night now.

My recent candidate ran out of steam 149/93000
