Linear OA(4¹⁴⁹, 239, F₄, 60) (dual of [239, 90, 61]-code), using 1 times truncation based on linear OA(4¹⁵⁰, 240, F₄, 61) (dual of [240, 90, 62]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁰, 60, F₆₄, 30) (dual of [60, 30, 31]-code or 60-arc in PG(29,64)), using
  - discarding factors / shortening the dual code based on linear OA(64³⁰, 64, F₆₄, 30) (dual of [64, 34, 31]-code or 64-arc in PG(29,64)), using
    - Reedâ€“Solomon code RS(34,64) [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]
