Weight Enumerators of Self-Orthogonal Codes over $GF$(3) [PDF]

SIAM Journal on Algebraic Discrete Methods, 1981
The Hamming and complete weight enumerators of maximally self-orthogonal codes over $GF$(3) of lengths $12m - 1$, $12m$ and $12m + 1$ are characterized. The results for length $12m + 1$ are believed to be new, while those for length $12m - 1$, and $12m$ have been considerably simplified.
