Good luck for your...

Sorry, Jean, but I sieved the exponents only for the interval n=0-10M.

I generated a new bunch (a few hundreds) of some extremely low weight Ks, out of which I'm currently processing 55 Ks to n=1M. On average there are only 24 candidates per million to be LLR tested...

k=59493015971 is now fully tested up to n=10M.
I'm stopping there and will take some other (even lower weighted) Ks instead.

If someone (Jean?) want's to take this k further, just feel free to do...

k's from the 2nd option ("LowNash2") have only been sieve for nmax=2M. Combining them with "LowNash1" would mean that these k need to be completely resieved for n=2-8M up to around p=14T. This...

k=380630849 and k=59493015971 have both been tested for n=0-2,000,000. No primes found. The later k is of extraordinarily low weight (Nash weight is 5), so I'll continue it a little bit further.

VBCurtis:
The values of k I'm working on are all sieved to pmax=12T yet, with nmax=10M.
If you want to do n=0...2M, then pmax=4T should be quite sufficient.
One could also think of using SBFactor...
