Linear OOA(2²³¹, 120, F₂, 3, 80) (dual of [(120, 3), 129, 81]-NRT-code), using strength reduction based on linear OOA(2²³¹, 120, F₂, 3, 81) (dual of [(120, 3), 129, 82]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁴⁷, 30, F₈, 3, 40) (dual of [(30, 3), 43, 41]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁴⁷, 34, F₈, 3, 40) (dual of [(34, 3), 55, 41]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,61P) [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]
