| Abstract: | The square-root bound for quadratic-residue codes of lengthn 1 (mod 4) is improved in several cases by graph-theoretic means.The results of this paper were presented at the Third International Workshop on Information Theory  Convolutional Codes; Multi-User Communication, Sochi, USSR, May 1987.Dedicated to Helmut Karzel on the occasion of his 60th birthday |
