Linear OA(4¹²⁶, 219, F₄, 48) (dual of [219, 93, 49]-code), using 1 times truncation based on linear OA(4¹²⁷, 220, F₄, 49) (dual of [220, 93, 50]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁴, 55, F₆₄, 24) (dual of [55, 31, 25]-code or 55-arc in PG(23,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁴, 64, F₆₄, 24) (dual of [64, 40, 25]-code or 64-arc in PG(23,64)), using
    - Reedâ€“Solomon code RS(40,64) [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]
