Linear OA(4¹⁷⁵, 196, F₄, 105) (dual of [196, 21, 106]-code), using 2 times truncation based on linear OA(4¹⁷⁷, 198, F₄, 107) (dual of [198, 21, 108]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁶, 33, F₆₄, 26) (dual of [33, 7, 27]-code or 33-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(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]
