Linear OOA(2²³⁹, 143, F₂, 3, 70) (dual of [(143, 3), 190, 71]-NRT-code), using 1 step truncation based on linear OOA(2²⁴⁰, 144, F₂, 3, 71) (dual of [(144, 3), 192, 72]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁴⁴, 36, F₈, 3, 35) (dual of [(36, 3), 64, 36]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁴⁴, 45, F₈, 3, 35) (dual of [(45, 3), 91, 36]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,99P) [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]
