Classification of ternary maximal self-orthogonal codes of length 25

Makoto Araya, Masaaki Harada

Ternary maximal self-orthogonal codes have been classified for lengths up to $24$ . In this note, we provide a complete classification of ternary maximal self-orthogonal codes of le…

Double Toeplitz codes and their average weight enumerators

Masaaki Harada, Keito Yamaguchi

Recently, double Toeplitz codes have been introduced as a generalization of double circulant codes. In this paper, we study the average weight enumerators of double Toeplitz codes.…

Ternary near-extremal self-dual codes of lengths $36$ , $48$ and $60$

Masaaki Harada

For lengths $36$ , $48$ and $60$ , we construct new ternary near-extremal self-dual codes with weight enumerators for which no ternary near-extremal self-dual codes were previously k…
