Linear OA(3¹⁵⁶, 284, F₃, 50) (dual of [284, 128, 51]-code), using 1 times truncation based on linear OA(3¹⁵⁷, 285, F₃, 51) (dual of [285, 128, 52]-code), using

concatenation of two codes [i] based on
1. linear OA(81²⁵, 57, F₈₁, 25) (dual of [57, 32, 26]-code or 57-arc in PG(24,81)), using
  - discarding factors / shortening the dual code based on linear OA(81²⁵, 81, F₈₁, 25) (dual of [81, 56, 26]-code or 81-arc in PG(24,81)), using
    - Reedâ€“Solomon code RS(56,81) [i]
2. linear OA(3¹, 5, F₃, 1) (dual of [5, 4, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
