Linear OA(4¹³⁸, 231, F₄, 54) (dual of [231, 93, 55]-code), using 1 times truncation based on linear OA(4¹³⁹, 232, F₄, 55) (dual of [232, 93, 56]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁷, 58, F₆₄, 27) (dual of [58, 31, 28]-code or 58-arc in PG(26,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁷, 64, F₆₄, 27) (dual of [64, 37, 28]-code or 64-arc in PG(26,64)), using
    - Reedâ€“Solomon code RS(37,64) [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]
