Effectively I will be triple checking n<260K but that part of the effort is fairly small with today's processors so I'm including all of it.

If anyone has any update on such an effort let me know.
k=39 was double checked to at least n=1.263M. Other searchers originally tested that k for n <= 1.263M (https://www.mersenneforum.org/showpo...&postcount=157), and when I took it over, I double checked everything starting from n=1 and posted the residues at: https://www.mersenneforum.org/showpo...&postcount=953
