Linear OA(4¹¹⁷, 150, F₄, 58) (dual of [150, 33, 59]-code), using strength reduction based on linear OA(4¹¹⁷, 150, F₄, 59) (dual of [150, 33, 60]-code), using

concatenation of two codes [i] based on
1. linear OA(64¹⁹, 30, F₆₄, 19) (dual of [30, 11, 20]-code or 30-arc in PG(18,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹⁹, 64, F₆₄, 19) (dual of [64, 45, 20]-code or 64-arc in PG(18,64)), using
    - Reedâ€“Solomon code RS(45,64) [i]
2. linear OA(4², 5, F₄, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,4)), using
  - extended Reedâ€“Solomon code RS_e(3,4) [i]
  - Hamming code H(2,4) [i]
