Linear OA(2¹²³, 179, F₂, 38) (dual of [179, 56, 39]-code), using 1 times truncation based on linear OA(2¹²⁴, 180, F₂, 39) (dual of [180, 56, 40]-code), using

concatenation of two codes [i] based on
1. linear OA(16²², 36, F₁₆, 19) (dual of [36, 14, 20]-code), using
  - discarding factors / shortening the dual code based on linear OA(16²², 38, F₁₆, 19) (dual of [38, 16, 20]-code), using
    - extended algebraic-geometric code AG_e(F,18P) [i] based on function field F/F₁₆ with g(F) = 3 and N(F) ≥ 38, using
      - a function field by SÃ©mirat [i]
2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
