ab: Summary: Let $S$ be a class of fully defined functions of any number of
    variables that are defined and take values in the set
    $E_k=\{0,1,\dots,k-1\}$ and are self-dual under a given permutation on
    $E_k$. Let $S^*$ be the set of all partially defined $k$-valued
    functions that can be extended to functions from $S$. In this paper all
    closed classes (under superposition) that contain $S$ and are contained
    in $S^*$ are described for the case when permutation is the product of
    non-intersecting cycles of the same length.
