Linear OA(4¹²⁸, 161, F₄, 66) (dual of [161, 33, 67]-code), using 1 times truncation based on linear OA(4¹²⁹, 162, F₄, 67) (dual of [162, 33, 68]-code), using

concatenation of two codes [i] based on
1. linear OA(64¹⁶, 27, F₆₄, 16) (dual of [27, 11, 17]-code or 27-arc in PG(15,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹⁶, 64, F₆₄, 16) (dual of [64, 48, 17]-code or 64-arc in PG(15,64)), using
    - Reedâ€“Solomon code RS(48,64) [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]
