Linear OA(4¹⁴², 166, F₄, 81) (dual of [166, 24, 82]-code), using 2 times truncation based on linear OA(4¹⁴⁴, 168, F₄, 83) (dual of [168, 24, 84]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁰, 28, F₆₄, 20) (dual of [28, 8, 21]-code or 28-arc in PG(19,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁰, 64, F₆₄, 20) (dual of [64, 44, 21]-code or 64-arc in PG(19,64)), using
    - Reedâ€“Solomon code RS(44,64) [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]
