Linear OA(4⁹⁵, 143, F₄, 40) (dual of [143, 48, 41]-code), using 1 times truncation based on linear OA(4⁹⁶, 144, F₄, 41) (dual of [144, 48, 42]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁰, 36, F₆₄, 20) (dual of [36, 16, 21]-code or 36-arc in PG(19,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁰, 64, F₆₄, 20) (dual of [64, 44, 21]-code or 64-arc in PG(19,64)), using
    - Reedâ€“Solomon code RS(44,64) [i]
2. linear OA(4¹, 4, F₄, 1) (dual of [4, 3, 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]
