Linear OA(4¹¹³, 146, F₄, 56) (dual of [146, 33, 57]-code), using 1 times code embedding in larger space based on linear OA(4¹¹², 145, F₄, 56) (dual of [145, 33, 57]-code), using

concatenation of two codes [i] based on
1. linear OA(64¹⁸, 29, F₆₄, 18) (dual of [29, 11, 19]-code or 29-arc in PG(17,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹⁸, 64, F₆₄, 18) (dual of [64, 46, 19]-code or 64-arc in PG(17,64)), using
    - Reedâ€“Solomon code RS(46,64) [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]
