Linear OA(4¹⁴², 184, F₄, 70) (dual of [184, 42, 71]-code), using 1 times truncation based on linear OA(4¹⁴³, 185, F₄, 71) (dual of [185, 42, 72]-code), using

concatenation of two codes [i] based on
1. linear OA(64²³, 37, F₆₄, 23) (dual of [37, 14, 24]-code or 37-arc in PG(22,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²³, 64, F₆₄, 23) (dual of [64, 41, 24]-code or 64-arc in PG(22,64)), using
    - Reedâ€“Solomon code RS(41,64) [i]
2. linear OA(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
