Linear OOA(2¹³⁸, 38, F₂, 5, 48) (dual of [(38, 5), 52, 49]-NRT-code), using OOA 2-folding based on linear OOA(2¹³⁸, 76, F₂, 3, 48) (dual of [(76, 3), 90, 49]-NRT-code), using

strength reduction [i] based on linear OOA(2¹³⁸, 76, F₂, 3, 49) (dual of [(76, 3), 90, 50]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(8²⁷, 19, F₈, 3, 24) (dual of [(19, 3), 30, 25]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(8²⁷, 24, F₈, 3, 24) (dual of [(24, 3), 45, 25]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(3;F,47P) [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]
