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

R 100 211199705992169 129/20795
R 100 211199705992169 130/20852

R 100 211199705992169 134/23358

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 join the search!
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...

Code:
 E   iter     I
-----------------
 52    32   66737
 58    37   47101
 60    12   37092
 66    13   15757
 82    48   13084
100  1109   42433
106  1452   67639
130  1829   85747
138  2477  101821
148  5000   37821
162  2336   62436
172     0       0
178   486   12511

S 732478130807511 106 152/107950 (13.115)
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
