Linear OA(4⁹⁷, 175, F₄, 36) (dual of [175, 78, 37]-code), using 1 times truncation based on linear OA(4⁹⁸, 176, F₄, 37) (dual of [176, 78, 38]-code), using

concatenation of two codes [i] based on
1. linear OA(64¹⁸, 44, F₆₄, 18) (dual of [44, 26, 19]-code or 44-arc in PG(17,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹⁸, 64, F₆₄, 18) (dual of [64, 46, 19]-code or 64-arc in PG(17,64)), using
    - Reedâ€“Solomon code RS(46,64) [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]
