Linear OA(4¹⁹⁰, 238, F₄, 97) (dual of [238, 48, 98]-code), using 2 times truncation based on linear OA(4¹⁹², 240, F₄, 99) (dual of [240, 48, 100]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁴, 40, F₆₄, 24) (dual of [40, 16, 25]-code or 40-arc in PG(23,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁴, 64, F₆₄, 24) (dual of [64, 40, 25]-code or 64-arc in PG(23,64)), using
    - Reedâ€“Solomon code RS(40,64) [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]
