Linear OA(3²⁰⁵, 449, F₃, 56) (dual of [449, 244, 57]-code), using 1 times truncation based on linear OA(3²⁰⁶, 450, F₃, 57) (dual of [450, 244, 58]-code), using

concatenation of two codes [i] based on
1. linear OA(81²⁹, 90, F₈₁, 28) (dual of [90, 61, 29]-code), using
  - discarding factors / shortening the dual code based on linear OA(81²⁹, 100, F₈₁, 28) (dual of [100, 71, 29]-code), using
    - extended algebraic-geometric code AG_e(F,71P) [i] based on function field F/F₈₁ with g(F) = 1 and N(F) ≥ 100, using
      - a function field by SÃ©mirat [i]
2. linear OA(3¹, 5, F₃, 1) (dual of [5, 4, 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]
