On cyclic reversible self-dual additive codes with odd length over Zeta(2)(2)
Several additive codes of odd length over Z(2)(2) are introduced. These codes are cyclic and reversible. Furthermore, they are self-dual under an appropriately selected binary-valued inner product. Some binary derivatives of these codes have good parameters. Alt cyclic and reversible [5, 2.5, 3] additive codes over Z(2)(2) are isomorphic and possess interesting properties.
