Linear OA(2¹⁰¹, 149, F₂, 32) (dual of [149, 48, 33]-code), using 1 times truncation based on linear OA(2¹⁰², 150, F₂, 33) (dual of [150, 48, 34]-code), using

concatenation of two codes [i] based on
1. linear OA(16¹⁸, 30, F₁₆, 16) (dual of [30, 12, 17]-code), using
  - discarding factors / shortening the dual code based on linear OA(16¹⁸, 33, F₁₆, 16) (dual of [33, 15, 17]-code), using
    - extended algebraic-geometric code AG_e(F,16P) [i] based on function field F/F₁₆ with g(F) = 2 and N(F) ≥ 33, 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]
