Linear OOA(3⁵⁸, 42, F₃, 2, 28) (dual of [(42, 2), 26, 29]-NRT-code), using strength reduction based on linear OOA(3⁵⁸, 42, F₃, 2, 29) (dual of [(42, 2), 26, 30]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(9¹⁵, 14, F₉, 2, 14) (dual of [(14, 2), 13, 15]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(9¹⁵, 16, F₉, 2, 14) (dual of [(16, 2), 17, 15]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,17P) [i] based on function field F/F₉ with g(F) = 1 and N(F) ≥ 16, 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]
