Thread: Yet another LLR bug View Single Post

Time : 1.728 sec. Starting Lucas sequence 2^21954+77899 is Lucas PRP, Starting Frobenius test sequence 2^21954+77899 is Frobenius PRP! (P = 4, Q = 2, D = 8) Time : 6.928 sec. But for 10^500+961 it doesn't run a Lucas or Frobenius sequence and instead says the number is not prime. So I think it really is a bug. Last fiddled with by nuggetprime on 2011-02-18 at 17:53
