Linear OA(3¹⁴⁹, 215, F₃, 56) (dual of [215, 66, 57]-code), using 1 times truncation based on linear OA(3¹⁵⁰, 216, F₃, 57) (dual of [216, 66, 58]-code), using

concatenation of two codes [i] based on
1. linear OA(27³², 54, F₂₇, 28) (dual of [54, 22, 29]-code), using
  - discarding factors / shortening the dual code based on linear OA(27³², 64, F₂₇, 28) (dual of [64, 32, 29]-code), using
    - extended algebraic-geometric code AG_e(F,35P) [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]
