Linear OA(2¹⁹⁷, 347, F₂, 50) (dual of [347, 150, 51]-code), using 1 times truncation based on linear OA(2¹⁹⁸, 348, F₂, 51) (dual of [348, 150, 52]-code), using

concatenation of two codes [i] based on
1. linear OA(32²⁸, 58, F₃₂, 25) (dual of [58, 30, 26]-code), using
  - discarding factors / shortening the dual code based on linear OA(32²⁸, 63, F₃₂, 25) (dual of [63, 35, 26]-code), using
    - algebraic-geometric code AG(F,37P) [i] based on function field F/F₃₂ with g(F) = 3 and N(F) ≥ 64, using
      - a function field by SÃ©mirat [i]
2. linear OA(2¹, 6, F₂, 1) (dual of [6, 5, 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]
