Linear OOA(2²⁵⁴, 143, F₂, 3, 80) (dual of [(143, 3), 175, 81]-NRT-code), using 1 step truncation based on linear OOA(2²⁵⁵, 144, F₂, 3, 81) (dual of [(144, 3), 177, 82]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁴⁹, 36, F₈, 3, 40) (dual of [(36, 3), 59, 41]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁴⁹, 45, F₈, 3, 40) (dual of [(45, 3), 86, 41]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,94P) [i] based on function field F/F₈ with g(F) = 9 and N(F) ≥ 45, using
      - an explicitly constructive algebraic function field [i]
2. linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 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]
