Watched these forums for a long time and finally decided its time to get involved with some of these conjectures.
I'll try taking R866 up to 200k

Think I've had a large case of beginners luck!

8*866^108590-1 is prime.

Last k eliminated so R866 is now proven

Beginners luck or not, it's nice to eliminate another pesky 1ker.
It is also eligible for the Top5000 list.
