Linear OA(2¹⁴³, 199, F₂, 44) (dual of [199, 56, 45]-code), using 1 times truncation based on linear OA(2¹⁴⁴, 200, F₂, 45) (dual of [200, 56, 46]-code), using

concatenation of two codes [i] based on
1. linear OA(16²⁶, 40, F₁₆, 22) (dual of [40, 14, 23]-code), using
  - discarding factors / shortening the dual code based on linear OA(16²⁶, 45, F₁₆, 22) (dual of [45, 19, 23]-code), using
    - extended algebraic-geometric code AG_e(F,22P) [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
      - a function field by GarcÃa and Quoos [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]
