In the Prelab section of this chapter, we introduced the notions of quadratic residue and quadratic nonresidue. We repeat the definitions here:
The quadratic residues modulo m are the integers relatively prime to m which are congruent to squares modulo m.
The integers relatively prime to m which are not congruent to a square modulo m are the quadratic nonresidues.
