Linear OA(4¹⁸⁶, 207, F₄, 112) (dual of [207, 21, 113]-code), using 3 times truncation based on linear OA(4¹⁸⁹, 210, F₄, 115) (dual of [210, 21, 116]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁸, 35, F₆₄, 28) (dual of [35, 7, 29]-code or 35-arc in PG(27,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁸, 64, F₆₄, 28) (dual of [64, 36, 29]-code or 64-arc in PG(27,64)), using
    - Reedâ€“Solomon code RS(36,64) [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]
