Linear OA(4¹⁵³, 213, F₄, 69) (dual of [213, 60, 70]-code), using 2 times truncation based on linear OA(4¹⁵⁵, 215, F₄, 71) (dual of [215, 60, 72]-code), using

concatenation of two codes [i] based on
1. linear OA(64²³, 43, F₆₄, 23) (dual of [43, 20, 24]-code or 43-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
  - extended Reedâ€“Solomon code RS_e(3,4) [i]
  - Hamming code H(2,4) [i]
