Formally self-dual even codes have recentlybeen studied. Double circulant even codes are a family of suchcodes and almost all known extremal formally self-dual even codesare of this form. In this paper, we classify all extremal doublecirculant formally self-dual even codes which are not self-dual.We also investigate the existence of near-extremal formally self-dualeven codes.
