I see. But then, how should we determine quadratic residuosity in Sage? (for tractible inputs) > I don't think this is evidence of a bug, because t2 is not prime. It is > only when n is is an odd prime that kronecker(a,n) tells you whether a is a > quadratic residue. See the wikipedia

I don't think this is evidence of a bug, because t2 is not prime. It is only when n is is an odd prime that kronecker(a,n) tells you whether a is a quadratic residue. See the wikipedia article on Kronecker symbol . On Wednesday, May 6, 2020 at
