Linear OA(4¹⁴², 199, F₄, 64) (dual of [199, 57, 65]-code), using 1 times truncation based on linear OA(4¹⁴³, 200, F₄, 65) (dual of [200, 57, 66]-code), using

concatenation of two codes [i] based on
1. linear OA(64²¹, 40, F₆₄, 21) (dual of [40, 19, 22]-code or 40-arc in PG(20,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²¹, 64, F₆₄, 21) (dual of [64, 43, 22]-code or 64-arc in PG(20,64)), using
    - Reedâ€“Solomon code RS(43,64) [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]
