Linear OA(2²²⁷, 419, F₂, 56) (dual of [419, 192, 57]-code), using 1 times truncation based on linear OA(2²²⁸, 420, F₂, 57) (dual of [420, 192, 58]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁸, 60, F₆₄, 28) (dual of [60, 32, 29]-code or 60-arc in PG(27,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁸, 64, F₆₄, 28) (dual of [64, 36, 29]-code or 64-arc in PG(27,64)), using
    - Reedâ€“Solomon code RS(36,64) [i]
2. linear OA(2¹, 7, F₂, 1) (dual of [7, 6, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
