Linear OA(4²¹⁶, 255, F₄, 120) (dual of [255, 39, 121]-code), using 3 times truncation based on linear OA(4²¹⁹, 258, F₄, 123) (dual of [258, 39, 124]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁰, 43, F₆₄, 30) (dual of [43, 13, 31]-code or 43-arc in PG(29,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁰, 64, F₆₄, 30) (dual of [64, 34, 31]-code or 64-arc in PG(29,64)), using
    - Reedâ€“Solomon code RS(34,64) [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]
