Linear OA(4⁷², 80, F₄, 50) (dual of [80, 8, 51]-code), using strength reduction based on linear OA(4⁷², 80, F₄, 51) (dual of [80, 8, 52]-code), using

concatenation of two codes [i] based on
1. linear OA(16¹², 16, F₁₆, 12) (dual of [16, 4, 13]-code or 16-arc in PG(11,16)), using
  - Reedâ€“Solomon code RS(4,16) [i]
2. linear OA(4³, 5, F₄, 3) (dual of [5, 2, 4]-code or 5-arc in PG(2,4) or 5-cap in PG(2,4)), using
  - extended Reedâ€“Solomon code RS_e(2,4) [i]
  - Simplex code S(2,4) [i]
