Linear OOA(2¹⁸⁹, 127, F₂, 2, 70) (dual of [(127, 2), 65, 71]-NRT-code), using 1 step truncation based on linear OOA(2¹⁹⁰, 128, F₂, 2, 71) (dual of [(128, 2), 66, 72]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁴², 32, F₈, 2, 35) (dual of [(32, 2), 22, 36]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁴², 34, F₈, 2, 35) (dual of [(34, 2), 26, 36]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,32P) [i] based on function field F/F₈ with g(F) = 7 and N(F) ≥ 34, using
      - a function field by SÃ©mirat [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]
