Linear OA(4¹⁷¹, 219, F₄, 85) (dual of [219, 48, 86]-code), using 1 times truncation based on linear OA(4¹⁷², 220, F₄, 86) (dual of [220, 48, 87]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁸, 44, F₆₄, 28) (dual of [44, 16, 29]-code or 44-arc in PG(27,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁸, 64, F₆₄, 28) (dual of [64, 36, 29]-code or 64-arc in PG(27,64)), using
    - Reedâ€“Solomon code RS(36,64) [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]
