Most coding theory experts date the origin of the subject with the 1948 publication of A
Mathematical Theory of Communication by Claude Shannon. Since then, coding theory has …

In this paper, all extremal Type I and Type III codes of length 60 with an automorphism of
order 29 are classified up to equivalence. In both cases, it has been proven that there are …

Let Zk be the ring of integers modulo k, where k is a positive integer greater than 1. AZ k-
code C of length n is a Zk-submodule of Zn k. A code C is self-dual if C ¼ C?, where the dual …

The aim of this work is to describe the structure and properties of the binary isodual codes
having automorphisms of odd prime order and to present a method for their construction. As …

In this paper we show the usability of the Gray code with constant weight words for
computing linear combinations of codewords. This can lead to a big improvement of the …

The paper presents the next step on the complete classification of all optimal binary selfdual
codes of length 52 that possess an automorphism of odd prime order. Applying the method …
