Quadratic residue code

Template:Binary linear code type
Definition
Let be a prime. The quadratic residue code associated with
is the binary linear code defined as follows:
- The underlying set is the set
- The subspace involved is the subspace generated by all translates of the set of quadratic non-residues
In other words, it is a cyclic code with generator polynomial being the generating function for the quadratic non-residues.
