Linear OOA(3¹⁴³, 63, F₃, 3, 74) (dual of [(63, 3), 46, 75]-NRT-code), using strength reduction based on linear OOA(3¹⁴³, 63, F₃, 3, 75) (dual of [(63, 3), 46, 76]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(9⁴⁰, 21, F₉, 3, 37) (dual of [(21, 3), 23, 38]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(9⁴⁰, 28, F₉, 3, 37) (dual of [(28, 3), 44, 38]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,46P) [i] based on function field F/F₉ with g(F) = 3 and N(F) ≥ 28, using
      - the Hermitian function field over F₉ [i]
2. linear OA(3¹, 3, F₃, 1) (dual of [3, 2, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
