Linear OA(2¹⁷⁵, 349, F₂, 42) (dual of [349, 174, 43]-code), using 1 times truncation based on linear OA(2¹⁷⁶, 350, F₂, 43) (dual of [350, 174, 44]-code), using

concatenation of two codes [i] based on
1. linear OA(64²¹, 50, F₆₄, 21) (dual of [50, 29, 22]-code or 50-arc in PG(20,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²¹, 64, F₆₄, 21) (dual of [64, 43, 22]-code or 64-arc in PG(20,64)), using
    - Reedâ€“Solomon code RS(43,64) [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]
