Linear OA(4¹⁵⁸, 251, F₄, 64) (dual of [251, 93, 65]-code), using 1 times truncation based on linear OA(4¹⁵⁹, 252, F₄, 65) (dual of [252, 93, 66]-code), using

concatenation of two codes [i] based on
1. linear OA(64³², 63, F₆₄, 32) (dual of [63, 31, 33]-code or 63-arc in PG(31,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³², 64, F₆₄, 32) (dual of [64, 32, 33]-code or 64-arc in PG(31,64)), using
    - Reedâ€“Solomon code RS(32,64) [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]
