Linear OOA(2²¹⁹, 120, F₂, 3, 72) (dual of [(120, 3), 141, 73]-NRT-code), using strength reduction based on linear OOA(2²¹⁹, 120, F₂, 3, 73) (dual of [(120, 3), 141, 74]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁴³, 30, F₈, 3, 36) (dual of [(30, 3), 47, 37]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁴³, 34, F₈, 3, 36) (dual of [(34, 3), 59, 37]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,65P) [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
