Some Extremal Self-Dual Codes and Unimodular Lattices in Dimension 40
Stefka Bouyuklieva, Iliya Bouyukliev, Masaaki Harada
In this paper, binary extremal singly even self-dual codes of length 40 and extremal odd unimodular lattices in dimension 40 are studied. We give a classification of extremal singl…
On the classification of binary self-dual [44,22,8] codes with an automorphism of order 3 or 7
Stefka Bouyuklieva, Nikolay Yankov, Radka Russeva
All binary self-dual [44,22,8] codes with an automorphism of order 3 or 7 are classified. In this way we complete the classification of extremal self-dual codes of length 44 having…
Singly-even self-dual codes with minimal shadow
Stefka Bouyuklieva, Wolfgang Willems
In this note we investigate extremal singly-even self-dual codes with minimal shadow. For particular parameters we prove non-existence of such codes. By a result of Rains \cite{Rai…
An Algorithm for Classification of Binary Self-Dual Codes
Stefka Bouyuklieva, Iliya Bouyukliev
An efficient algorithm for classification of binary self-dual codes is presented. As an application, a complete classification of the self-dual codes of length 38 is given.
