Linear OOA(2¹²⁴, 39, F₂, 4, 52) (dual of [(39, 4), 32, 53]-NRT-code), using OOA 2-folding based on linear OOA(2¹²⁴, 78, F₂, 2, 52) (dual of [(78, 2), 32, 53]-NRT-code), using

strength reduction [i] based on linear OOA(2¹²⁴, 78, F₂, 2, 53) (dual of [(78, 2), 32, 54]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4³⁶, 26, F₄, 2, 26) (dual of [(26, 2), 16, 27]-NRT-code), using
    - algebraic-geometric NRT-code AG(2;F,25P) [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]
