Linear OA(4²²⁷, 308, F₄, 105) (dual of [308, 81, 106]-code), using 2 times truncation based on linear OA(4²²⁹, 310, F₄, 107) (dual of [310, 81, 108]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁵, 62, F₆₄, 35) (dual of [62, 27, 36]-code or 62-arc in PG(34,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁵, 64, F₆₄, 35) (dual of [64, 29, 36]-code or 64-arc in PG(34,64)), using
    - Reedâ€“Solomon code RS(29,64) [i]
2. linear OA(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
