Linear OA(4¹⁶², 213, F₄, 78) (dual of [213, 51, 79]-code), using 2 times truncation based on linear OA(4¹⁶⁴, 215, F₄, 80) (dual of [215, 51, 81]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁶, 43, F₆₄, 26) (dual of [43, 17, 27]-code or 43-arc in PG(25,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁶, 64, F₆₄, 26) (dual of [64, 38, 27]-code or 64-arc in PG(25,64)), using
    - Reedâ€“Solomon code RS(38,64) [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]
