(264031 decimal digits) 76*311^135562+1 is prime! (337926 decimal digits) Note: This makes both bases 1kers. MyDog Last fiddled with by MyDogBuster on 2014-11-28 at 02:15 Reason: S311, too

I suggest taking 3.7.8 for a spin. You can compare the results then choose if you want to upgrade. 3.7.8 might be much faster than 3.4.3.
