Linear OA(4¹⁵¹, 172, F₄, 89) (dual of [172, 21, 90]-code), using 2 times truncation based on linear OA(4¹⁵³, 174, F₄, 91) (dual of [174, 21, 92]-code), using

concatenation of two codes [i] based on
1. linear OA(64²², 29, F₆₄, 22) (dual of [29, 7, 23]-code or 29-arc in PG(21,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²², 64, F₆₄, 22) (dual of [64, 42, 23]-code or 64-arc in PG(21,64)), using
    - Reedâ€“Solomon code RS(42,64) [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]
