Linear OA(4¹¹³, 191, F₄, 44) (dual of [191, 78, 45]-code), using 1 times truncation based on linear OA(4¹¹⁴, 192, F₄, 45) (dual of [192, 78, 46]-code), using

concatenation of two codes [i] based on
1. linear OA(64²², 48, F₆₄, 22) (dual of [48, 26, 23]-code or 48-arc in PG(21,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²², 64, F₆₄, 22) (dual of [64, 42, 23]-code or 64-arc in PG(21,64)), using
    - Reedâ€“Solomon code RS(42,64) [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]
