Linear OA(4¹⁹⁹, 238, F₄, 109) (dual of [238, 39, 110]-code), using 2 times truncation based on linear OA(4²⁰¹, 240, F₄, 111) (dual of [240, 39, 112]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁷, 40, F₆₄, 27) (dual of [40, 13, 28]-code or 40-arc in PG(26,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁷, 64, F₆₄, 27) (dual of [64, 37, 28]-code or 64-arc in PG(26,64)), using
    - Reedâ€“Solomon code RS(37,64) [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]
