[QUOTE=Cruelty;145900]BTW: What is the weight of this "k"?
[/QUOTE]

k=19709699 has a Nash weight of 26.
see [url]www.rieselprime.org[/url] in the Data Section and the 10^7-10^8 range.
all listed k's are given with their Nash-weight there on all data pages.
there are many others not searched yet or at lower levels.
please report the searched ranges if you try one of these!
i'm planning to include much more low weight k's in the future.
