Linear OA(4²³⁷, 303, F₄, 117) (dual of [303, 66, 118]-code), using 2 times truncation based on linear OA(4²³⁹, 305, F₄, 119) (dual of [305, 66, 120]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁹, 61, F₆₄, 39) (dual of [61, 22, 40]-code or 61-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(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
