Linear OOA(3²⁴¹, 236, F₃, 2, 74) (dual of [(236, 2), 231, 75]-NRT-code), using strength reduction based on linear OOA(3²⁴¹, 236, F₃, 2, 75) (dual of [(236, 2), 231, 76]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(27⁴¹, 59, F₂₇, 2, 37) (dual of [(59, 2), 77, 38]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(27⁴¹, 64, F₂₇, 2, 37) (dual of [(64, 2), 87, 38]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,90P) [i] based on function field F/F₂₇ with g(F) = 4 and N(F) ≥ 64, using
      - a function field by SÃ©mirat [i]
2. linear OA(3¹, 4, F₃, 1) (dual of [4, 3, 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]
