Linear OA(2²⁰³, 419, F₂, 48) (dual of [419, 216, 49]-code), using 1 times truncation based on linear OA(2²⁰⁴, 420, F₂, 49) (dual of [420, 216, 50]-code), using

concatenation of two codes [i] based on
1. linear OA(64²⁴, 60, F₆₄, 24) (dual of [60, 36, 25]-code or 60-arc in PG(23,64)), using
  - discarding factors / shortening the dual code based on linear OA(64²⁴, 64, F₆₄, 24) (dual of [64, 40, 25]-code or 64-arc in PG(23,64)), using
    - Reedâ€“Solomon code RS(40,64) [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]
