In this note, the existence of self-dual codes and formally self-dual even codes is investigated. A construction for self-dual codes is presented, based on extending generator matrices. Using this method, a singly-even self-dual [70, 35, code is constructed from a self-dual code of length 68. This i

The classi"cation of all self-dual codes over 9 of length up to 15 and Type II codes of length 16 is known. In this note, we give a method to classify Type IV self-dual codes over 9 . As an application, we present the classi"cation of Type IV self-dual codes of length 16. There are exactly 11 inequ

In this letter, double circulant [68, 34, 13] codes with two different weight distributions are presented. In addition, it is shown that codes with one of these distributions can be extended to a formally self-dual even [70, 35, 14] code. This is the first example of a formally self-dual even code
