Linear OOA(2¹⁶³, 75, F₂, 3, 68) (dual of [(75, 3), 62, 69]-NRT-code), using strength reduction based on linear OOA(2¹⁶³, 75, F₂, 3, 69) (dual of [(75, 3), 62, 70]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4⁴⁴, 25, F₄, 3, 34) (dual of [(25, 3), 31, 35]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(4⁴⁴, 26, F₄, 3, 34) (dual of [(26, 3), 34, 35]-NRT-code), using
    - algebraic-geometric NRT-code AG(3;F,43P) [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]
