New extremal binary self-dual codes of length 68 from quadratic residue codes over F 2+uF2+u2F2

Published: 01 September 2014 Publication History

Abstract

In this work, quadratic residue codes over the ring F"2+uF"2+u^2F"2 with u^3=u are considered. A duality and distance preserving Gray map from F"2+uF"2+u^2F"2 to F"2^3 is defined. By using quadratic double circulant, quadratic bordered double circulant constructions and their extensions self-dual codes of different lengths are obtained. As Gray images of these codes and their extensions, a substantial number of new extremal self-dual binary codes are found. More precisely, thirty two new extremal binary self-dual codes of length 68, 363 Type I codes of parameters [72,36,12], a Type II [72,36,12] code and a Type II [96,48,16] code with new weight enumerators are obtained through these constructions. The results are tabulated.
