Linear OOA(2²³⁸, 75, F₂, 5, 66) (dual of [(75, 5), 137, 67]-NRT-code), using OOA 3-folding based on linear OOA(2²³⁸, 225, F₂, 2, 66) (dual of [(225, 2), 212, 67]-NRT-code), using

strength reduction [i] based on linear OOA(2²³⁸, 225, F₂, 2, 67) (dual of [(225, 2), 212, 68]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(16³⁷, 45, F₁₆, 2, 33) (dual of [(45, 2), 53, 34]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,56P) [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
      - a function field by GarcÃa and Quoos [i]
  2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 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]
