Linear OA(4¹⁵⁹, 210, F₄, 76) (dual of [210, 51, 77]-code), using strength reduction based on linear OA(4¹⁵⁹, 210, F₄, 77) (dual of [210, 51, 78]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁵, 42, F₆₄, 25) (dual of [42, 17, 26]-code or 42-arc in PG(24,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁵, 64, F₆₄, 25) (dual of [64, 39, 26]-code or 64-arc in PG(24,64)), using
    - Reedâ€“Solomon code RS(39,64) [i]
2. linear OA(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
