Linear OA(4¹²¹, 211, F₄, 46) (dual of [211, 90, 47]-code), using 1 times truncation based on linear OA(4¹²², 212, F₄, 47) (dual of [212, 90, 48]-code), using

concatenation of two codes [i] based on
1. linear OA(64²³, 53, F₆₄, 23) (dual of [53, 30, 24]-code or 53-arc in PG(22,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²³, 64, F₆₄, 23) (dual of [64, 41, 24]-code or 64-arc in PG(22,64)), using
    - Reedâ€“Solomon code RS(41,64) [i]
2. linear OA(4¹, 4, F₄, 1) (dual of [4, 3, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(4¹, s, F₄, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
