Let X and A be sets and α: X → A a map between them. We call a map µ: X × X × X → A an approximate Mal’tsev operation with approximation α, if it satisfies µ(x, y, y) = α(x) = µ(y, y, x) for all x, y ∈ X. Note that if A = X and the approximation α is an identity map, then µ becomes an ordinary Mal’tsev operation. We
