Linear OA(4⁹⁹, 120, F₄, 54) (dual of [120, 21, 55]-code), using strength reduction based on linear OA(4⁹⁹, 120, F₄, 55) (dual of [120, 21, 56]-code), using

concatenation of two codes [i] based on
1. linear OA(64¹³, 20, F₆₄, 13) (dual of [20, 7, 14]-code or 20-arc in PG(12,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹³, 64, F₆₄, 13) (dual of [64, 51, 14]-code or 64-arc in PG(12,64)), using
    - Reedâ€“Solomon code RS(51,64) [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]
