Hi, thank you for your help. I have changed it to: v=1; w=1; x=1 #Berechnung von Vp,t noch ohne modulo q for i in range(1,((p-1)/2)+1): v=z^i-z^(-i)%q R=Integers(q) w=R(v)^(i^expo) x=(x*w)%q it give the same results like the faster algorithm and now I can compute primes with a higher value w

One more question: Is there a command to get the total time for all computings in one notebook sheet(?)? I know the command time for one cell of sage. Daniel Köhl --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscr

Hi, I tried a little bit and I think I have programmed the test for Vandiver´s conjecture like Buhler et. al. described it in their papers. I have both ways the slow and fast in the notebook of sage. I will show it to you here and hope you can eventually show me some points were are mistakes, if
