Linear OA(4²³⁸, 286, F₄, 129) (dual of [286, 48, 130]-code), using 2 times truncation based on linear OA(4²⁴⁰, 288, F₄, 131) (dual of [288, 48, 132]-code), using

concatenation of two codes [i] based on
1. linear OA(64³², 48, F₆₄, 32) (dual of [48, 16, 33]-code or 48-arc in PG(31,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³², 64, F₆₄, 32) (dual of [64, 32, 33]-code or 64-arc in PG(31,64)), using
    - Reedâ€“Solomon code RS(32,64) [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
