No, the method of Agrawal, Kayal and Saxena is still in a theoretical state and we have to wait for an efficient algorithm to apply it. I used an old Miller-Rabin method. By testing the strong probable primality to some bases, in particular ranges we can have the certainty that the number is prime. See for example http://www.utm.edu/research/primes/prove/prove2_3.html Franco _______________________________________________ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal
