Linear OA(4²³⁸, 280, F₄, 133) (dual of [280, 42, 134]-code), using 2 times truncation based on linear OA(4²⁴⁰, 282, F₄, 135) (dual of [282, 42, 136]-code), using

concatenation of two codes [i] based on
1. linear OA(64³³, 47, F₆₄, 33) (dual of [47, 14, 34]-code or 47-arc in PG(32,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³³, 64, F₆₄, 33) (dual of [64, 31, 34]-code or 64-arc in PG(32,64)), using
    - Reedâ€“Solomon code RS(31,64) [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
