Abstract :
For p eqiv pm 1 \\pmod {8} there are two binary codes, Q(p) and N(p) , each an extended quadratic residue code of length p+1 and dimension (p+1)/2 . The existence of double circulant generator matrices for these codes is investigated. A possibly infinite family of primes p is presented for which Q(p) and N(p) must have double circulant generator matrices. Two counterexamples prove the construction is not always possible.
