Linear OOA(2¹⁴⁹, 134, F₂, 2, 44) (dual of [(134, 2), 119, 45]-NRT-code), using 1 step truncation based on linear OOA(2¹⁵⁰, 135, F₂, 2, 45) (dual of [(135, 2), 120, 46]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16²⁴, 27, F₁₆, 2, 22) (dual of [(27, 2), 30, 23]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(16²⁴, 33, F₁₆, 2, 22) (dual of [(33, 2), 42, 23]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,43P) [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]
