The following table (sequence A096008 in the OEIS) lists the quadratic residues mod 1 to 75 (a red number means it is not coprime to n). (For the quadratic residues coprime to n, see OEIS: A096103, and for nonzero quadratic residues, see OEIS: A046071.) Meer weergeven In number theory, an integer q is called a quadratic residue modulo n if it is congruent to a perfect square modulo n; i.e., if there exists an integer x such that: $${\displaystyle x^{2}\equiv q{\pmod {n}}.}$$ Meer weergeven Although quadratic residues appear to occur in a rather random pattern modulo n, and this has been exploited in such applications as acoustics and cryptography, … Meer weergeven The list of the number of quadratic residues modulo n, for n = 1, 2, 3 ..., looks like: 1, 2, 2, 2, 3, 4, 4, 3, 4, 6, 6, 4, 7, 8, 6, ...
