Abstract
In this paper, we give a precise description of Rains’ algorithm for classifying self-dual \(\mathbb {Z}_4\)-codes with a given residue code. We will use this to classify self-dual \(\mathbb {Z}_4\)-codes of length 20. A similar method is used to classify self-dual codes over \(\mathbb {F}_2+u\mathbb {F}_2\). We will update the table given by Han, Lee and Lee, of the data regarding the classification of self-dual codes over \(\mathbb {F}_2+u\mathbb {F}_2\).
