Extremal Self-Dual Codes with an Automorphism of Order 2

Abstract

A method to design binary self-dual codes with an automorphism of order two without fixed points is presented. Extremal self-dual codes with lengths 40; 42; 44; 54; 58; 68 are constructed. Many of them have weight enumerators for which extremal codes were previously not known to exist.
