Linear OOA(3⁸³, 56, F₃, 2, 42) (dual of [(56, 2), 29, 43]-NRT-code), using 1 step truncation based on linear OOA(3⁸⁴, 57, F₃, 2, 43) (dual of [(57, 2), 30, 44]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(9²³, 19, F₉, 2, 21) (dual of [(19, 2), 15, 22]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(9²³, 20, F₉, 2, 21) (dual of [(20, 2), 17, 22]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,18P) [i] based on function field F/F₉ with g(F) = 2 and N(F) ≥ 20, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(3¹, 3, F₃, 1) (dual of [3, 2, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
