Linear OA(4²¹³, 240, F₄, 126) (dual of [240, 27, 127]-code), using strength reduction based on linear OA(4²¹³, 240, F₄, 127) (dual of [240, 27, 128]-code), using

concatenation of two codes [i] based on
1. linear OA(64³¹, 40, F₆₄, 31) (dual of [40, 9, 32]-code or 40-arc in PG(30,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³¹, 64, F₆₄, 31) (dual of [64, 33, 32]-code or 64-arc in PG(30,64)), using
    - Reedâ€“Solomon code RS(33,64) [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]
