I did not do the work sequentially. I had done part of that range. Just a matter of luck.

Serge,

I understand your point, but one of the reasons I like prime testing/distributed computing is to be as efficient I can. I like and value efficiency.

Once you use the exe, is there a way to make it just search for GQ factors of GM factors. How do you produce an input file for LLR from the output of the program.

I don't completely understand your previous post (with the software bug). Do we need to re-do any ranges for a missed prime etc or are we good?

When checking in GM=1 and GQ=1 mode LLR does not write the factors unless factors for both GM=1 and GQ=1 have been found. Writing a script will not help because LLR does not output the factors.
