Linear OA(4¹⁶⁸, 189, F₄, 100) (dual of [189, 21, 101]-code), using 3 times truncation based on linear OA(4¹⁷¹, 192, F₄, 103) (dual of [192, 21, 104]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁵, 32, F₆₄, 25) (dual of [32, 7, 26]-code or 32-arc in PG(24,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁵, 64, F₆₄, 25) (dual of [64, 39, 26]-code or 64-arc in PG(24,64)), using
    - Reedâ€“Solomon code RS(39,64) [i]
2. linear OA(4³, 6, F₄, 3) (dual of [6, 3, 4]-code or 6-arc in PG(2,4) or 6-cap in PG(2,4)), using
  - hyperoval in PG(2,Â 4) [i]
  - the Hexacode [i]
