Linear OA(4¹⁵⁵, 185, F₄, 86) (dual of [185, 30, 87]-code), using 1 times truncation based on linear OA(4¹⁵⁶, 186, F₄, 87) (dual of [186, 30, 88]-code), using

concatenation of two codes [i] based on
1. linear OA(64²¹, 31, F₆₄, 21) (dual of [31, 10, 22]-code or 31-arc in PG(20,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²¹, 64, F₆₄, 21) (dual of [64, 43, 22]-code or 64-arc in PG(20,64)), using
    - Reedâ€“Solomon code RS(43,64) [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]
