Linear OA(4⁹³, 131, F₄, 42) (dual of [131, 38, 43]-code), using 1 times truncation based on linear OA(4⁹⁴, 132, F₄, 43) (dual of [132, 38, 44]-code), using

concatenation of two codes [i] based on
1. linear OA(16²⁵, 44, F₁₆, 21) (dual of [44, 19, 22]-code), using
  - discarding factors / shortening the dual code based on linear OA(16²⁵, 45, F₁₆, 21) (dual of [45, 20, 22]-code), using
    - extended algebraic-geometric code AG_e(F,23P) [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(4¹, 3, F₄, 1) (dual of [3, 2, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(4¹, s, F₄, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
