Abstract: We report on the three-loop unpolarized and polarized massive operator matrix elements, withsingle- and two-mass corrections, and the associated deep-inelastic massive Wilson coefficientsin the region $Q^2 \gg m_Q^2$ , the calculation of which has been completed recently. We also providefast and precise numerical representations of the massless Wilson coefficients, splitting functionsto tree-loop order, and target mass corrections in 𝑥-space well suited for QCD-fitting codes.
