Linear OA(3¹⁰⁸, 159, F₃, 42) (dual of [159, 51, 43]-code), using 1 times truncation based on linear OA(3¹⁰⁹, 160, F₃, 43) (dual of [160, 51, 44]-code), using

concatenation of two codes [i] based on
1. linear OA(27²³, 40, F₂₇, 21) (dual of [40, 17, 22]-code), using
  - discarding factors / shortening the dual code based on linear OA(27²³, 48, F₂₇, 21) (dual of [48, 25, 22]-code), using
    - extended algebraic-geometric code AG_e(F,26P) [i] based on function field F/F₂₇ with g(F) = 2 and N(F) ≥ 48, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(3¹, 4, F₃, 1) (dual of [4, 3, 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]
