Linear OA(4¹⁸⁵, 239, F₄, 91) (dual of [239, 54, 92]-code), using 1 times truncation based on linear OA(4¹⁸⁶, 240, F₄, 92) (dual of [240, 54, 93]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁰, 48, F₆₄, 30) (dual of [48, 18, 31]-code or 48-arc in PG(29,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁰, 64, F₆₄, 30) (dual of [64, 34, 31]-code or 64-arc in PG(29,64)), using
    - Reedâ€“Solomon code RS(34,64) [i]
2. linear OA(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
  - extended Reedâ€“Solomon code RS_e(3,4) [i]
  - Hamming code H(2,4) [i]
