Query: Permutation decoding of Z2Z4-linear codes   An alternative permutation decoding method is described which can be used for
any binary systematic encoding scheme, regardless whether the code is linear or
not. Thus, the method can be applied to some important codes such as
Z2Z4-linear codes, which are binary and, in general, nonlinear codes in the
usual sense. For this, it is proved that these codes allow a systematic
encoding scheme. As a particular example, this permutation decoding method is
applied to some Hadamard Z2Z4-linear codes.
