Hello,

hm, now I have a problem. I checked them again with my library (DecMath7, a library for Delphi), again I was told these are composites. The prp-test I used is defined:

// strong pseudo prime test of A to bases 2,3,5,7,11 and Pommerance,Bailie,Wagstaff test (strong lucas pseudo primality)
function NIsProbablePrime(const A: IInteger): Boolean; overload;

I never before got a composite result if other prp-tests say it is a prp. I will contact the author of the library about this numbers, most probable it is an error in the prp test. I used thsi library for 3 years, I have to check some GB of data again... I think I'm out for some time, sorry

best regards,

Matthias
