Linear OA(3¹⁶⁹, 223, F₃, 68) (dual of [223, 54, 69]-code), using 1 times truncation based on linear OA(3¹⁷⁰, 224, F₃, 69) (dual of [224, 54, 70]-code), using

concatenation of two codes [i] based on
1. linear OA(27³⁸, 56, F₂₇, 34) (dual of [56, 18, 35]-code), using
  - discarding factors / shortening the dual code based on linear OA(27³⁸, 64, F₂₇, 34) (dual of [64, 26, 35]-code), using
    - extended algebraic-geometric code AG_e(F,29P) [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]
