Linear OA(4²⁰¹, 228, F₄, 118) (dual of [228, 27, 119]-code), using strength reduction based on linear OA(4²⁰¹, 228, F₄, 119) (dual of [228, 27, 120]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁹, 38, F₆₄, 29) (dual of [38, 9, 30]-code or 38-arc in PG(28,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁹, 64, F₆₄, 29) (dual of [64, 35, 30]-code or 64-arc in PG(28,64)), using
    - Reedâ€“Solomon code RS(35,64) [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]
