Either there is a problem with dodeca_2_0.c or that PARI script:- \$ ../dodeca20 50 7170000000000000 7200000000000000 You can also find the k n values in results_dodeca.txt file ( These are 3-probable primes ) n=50, kmin=7170000000000000, kmax=7200000000000000, version=2.0 Starting the sieve... Using the first 9 primes to reduce the size of the sieve array The sieving is complete. Number of Prp tests=1567 Time=22 sec.
That is a new dodecaproth! I think somebody made a mistake when he searched this n value ( for this he used your tables!).
For my program: you have typed 10 times larger number than original!!!
Try again. For me it is correctly found this number!
