Linear OOA(3¹²⁸, 42, F₃, 4, 66) (dual of [(42, 4), 40, 67]-NRT-code), using OOA 2-folding based on linear OOA(3¹²⁸, 84, F₃, 2, 66) (dual of [(84, 2), 40, 67]-NRT-code), using

strength reduction [i] based on linear OOA(3¹²⁸, 84, F₃, 2, 67) (dual of [(84, 2), 40, 68]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(9³⁶, 28, F₉, 2, 33) (dual of [(28, 2), 20, 34]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,22P) [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]
