Published 18 Jun 2023 in math.CO, cs.IT, and math.IT | (2306.10451v1)
Abstract: In this note, we give basic properties of ternary four-negacirculant self-dual codes. By exhaustive computer search based on the properties, we complete a classification of ternary extremal four-negacirculant self-dual codes of lengths 40, 44, 48, 52 and 60.
