Linear OA(4¹⁰⁴, 143, F₄, 48) (dual of [143, 39, 49]-code), using 2 times truncation based on linear OA(4¹⁰⁶, 145, F₄, 50) (dual of [145, 39, 51]-code), using

concatenation of two codes [i] based on
1. linear OA(64¹⁶, 29, F₆₄, 16) (dual of [29, 13, 17]-code or 29-arc in PG(15,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹⁶, 64, F₆₄, 16) (dual of [64, 48, 17]-code or 64-arc in PG(15,64)), using
    - Reedâ€“Solomon code RS(48,64) [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]
