Linear OA(4¹²⁵, 164, F₄, 61) (dual of [164, 39, 62]-code), using 1 times truncation based on linear OA(4¹²⁶, 165, F₄, 62) (dual of [165, 39, 63]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁰, 33, F₆₄, 20) (dual of [33, 13, 21]-code or 33-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(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
  - extended Reedâ€“Solomon code RS_e(3,4) [i]
  - Hamming code H(2,4) [i]
