摘要：
The optimal minimal Euclidean norm of self-dual codes over Z(4) is known through length 24; the purpose of the present note is to determine the optimal minimal Hamming and Lee weights in this range. In the process, we classify all Lee-optimal codes of length 18, 21, 23, and 24. In particular, we find a total of 13 inequivalent codes with the same symmetrized weight enumerator as the Hensel-lifted Golay code. (C) 1999 Elsevier Science B.V. All rights reserved.
