Linear OA(2²¹⁷, 391, F₂, 54) (dual of [391, 174, 55]-code), using 1 times truncation based on linear OA(2²¹⁸, 392, F₂, 55) (dual of [392, 174, 56]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁷, 56, F₆₄, 27) (dual of [56, 29, 28]-code or 56-arc in PG(26,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁷, 64, F₆₄, 27) (dual of [64, 37, 28]-code or 64-arc in PG(26,64)), using
    - Reedâ€“Solomon code RS(37,64) [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]
