Abstract:In this paper, we study binary optimal odd formallyself-dual codes. All optimal odd formally self-dual codes areclassified for length up to 16. The highest minimum weight ofany odd formally self-dual codes of length up to 24 is determined. We also show that there is a unique linearcode for parameters 16, 8, 5] and 22, 11, 7], up to equivalence.
Keywords:Odd formally self-dual codes  [22  11  7] code
