Linear OA(4²⁴², 308, F₄, 120) (dual of [308, 66, 121]-code), using 2 times truncation based on linear OA(4²⁴⁴, 310, F₄, 122) (dual of [310, 66, 123]-code), using

concatenation of two codes [i] based on
1. linear OA(64⁴⁰, 62, F₆₄, 40) (dual of [62, 22, 41]-code or 62-arc in PG(39,64)), using
  - discarding factors / shortening the dual code based on linear OA(64⁴⁰, 64, F₆₄, 40) (dual of [64, 24, 41]-code or 64-arc in PG(39,64)), using
    - Reedâ€“Solomon code RS(24,64) [i]
2. linear OA(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
