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