Linear OA(3¹⁴⁰, 203, F₃, 54) (dual of [203, 63, 55]-code), using 1 times truncation based on linear OA(3¹⁴¹, 204, F₃, 55) (dual of [204, 63, 56]-code), using

concatenation of two codes [i] based on
1. linear OA(27³⁰, 51, F₂₇, 27) (dual of [51, 21, 28]-code), using
  - discarding factors / shortening the dual code based on linear OA(27³⁰, 52, F₂₇, 27) (dual of [52, 22, 28]-code), using
    - extended algebraic-geometric code AG_e(F,24P) [i] based on function field F/F₂₇ with g(F) = 3 and N(F) ≥ 52, 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]
