Linear OA(2¹⁶¹, 209, F₂, 52) (dual of [209, 48, 53]-code), using 1 times truncation based on linear OA(2¹⁶², 210, F₂, 53) (dual of [210, 48, 54]-code), using

concatenation of two codes [i] based on
1. linear OA(16³⁰, 42, F₁₆, 26) (dual of [42, 12, 27]-code), using
  - discarding factors / shortening the dual code based on linear OA(16³⁰, 45, F₁₆, 26) (dual of [45, 15, 27]-code), using
    - extended algebraic-geometric code AG_e(F,18P) [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 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]
