The standard Nash-weight was defined as n-values remaining after sieving the range 100001<=n<=110000 up to p=511.

So with srsieve the command
Code:
srsieve -n 100001 -N 110000 -P 511 "301*2^n-1"
prints 2254 candidates left for Riesel Base 2 k=301.

The small program 'nash' from T.Ritschel given here calculates a weight of 2158 for this k-value.

I'm using this program to show the Nash weights on www.rieselprime.de for all k-values.

Doing a script for some values should work with all bases and result in a compareable value for all.
