Linear OOA(2¹⁰⁸, 42, F₂, 4, 38) (dual of [(42, 4), 60, 39]-NRT-code), using OOA 2-folding based on linear OOA(2¹⁰⁸, 84, F₂, 2, 38) (dual of [(84, 2), 60, 39]-NRT-code), using

strength reduction [i] based on linear OOA(2¹⁰⁸, 84, F₂, 2, 39) (dual of [(84, 2), 60, 40]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(8²², 21, F₈, 2, 19) (dual of [(21, 2), 20, 20]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(8²², 24, F₈, 2, 19) (dual of [(24, 2), 26, 20]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,28P) [i] based on function field F/F₈ with g(F) = 3 and N(F) ≥ 24, using
        the Klein quartic over F₈ [i]
  2. linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
