THE BINARY SELF-DUAL CODES OF LENGTH UP TO 32 - A REVISED ENUMERATION

This paper presents a revised enumeration of the binary self-dual codes of length up to 32 given by Conway and Pless in 1978-1980. The list of 85 doubly-even self-dual codes of length 32 is essentially correct, but several of their descriptions need amending. The principal change is that there are 731 (not 664) inequivalent self-dual codes of length 30. Furthermore, there are three (not two) [28, 14, 6] and 13 (not eight) [30, 15, 6] self-dual codes. Some additional information is provided about the self-dual codes of length less than 32. © 1992.
