 There is exactly one computable \(m\)-degree \(\mathbf{0}_m\) other than \(\mathbf{0}\) and \(\mathbf{n}\)—i.e., \(\mathbf{0}_m = \textrm{deg}(A)\) for any computable set \(A \neq \emptyset, A\neq \mathbb{N}\). Additionally, \(\mathbf{0}_m\) is minimal in \(\mathcal{D}_m\) in the sense that \(\mathbf{0}_m \leq_m \mathbf{a}\) for all degrees \(\mathbf{a}\) other than \(\mathbf{0}\) and \(\mathbf{n}\).
