Linear OOA(2¹²¹, 38, F₂, 4, 50) (dual of [(38, 4), 31, 51]-NRT-code), using OOA 2-folding based on linear OOA(2¹²¹, 76, F₂, 2, 50) (dual of [(76, 2), 31, 51]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(2¹²¹, 77, F₂, 2, 50) (dual of [(77, 2), 33, 51]-NRT-code), using
- 1 step truncation [i] based on linear OOA(2¹²², 78, F₂, 2, 51) (dual of [(78, 2), 34, 52]-NRT-code), using
  - concatenation of two NRT-codes [i] based on
    1. linear OOA(4³⁵, 26, F₄, 2, 25) (dual of [(26, 2), 17, 26]-NRT-code), using
      - algebraic-geometric NRT-code AG(2;F,26P) [i] based on function field F/F₄ with g(F) = 10 and N(F) ≥ 27, using
        an explicitly constructive algebraic function field [i]
    2. linear OA(2¹, 3, F₂, 1) (dual of [3, 2, 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]
