Linear OA(4²⁵⁷, 278, F₄, 159) (dual of [278, 21, 160]-code), using 2 times code embedding in larger space based on linear OA(4²⁵⁵, 276, F₄, 159) (dual of [276, 21, 160]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁹, 46, F₆₄, 39) (dual of [46, 7, 40]-code or 46-arc in PG(38,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁹, 64, F₆₄, 39) (dual of [64, 25, 40]-code or 64-arc in PG(38,64)), using
    - Reedâ€“Solomon code RS(25,64) [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
