Linear OA(2²⁰⁵, 225, F₂, 85) (dual of [225, 20, 86]-code), using 3 times code embedding in larger space based on linear OA(2²⁰², 222, F₂, 85) (dual of [222, 20, 86]-code), using

2 times truncation [i] based on linear OA(2²⁰⁴, 224, F₂, 87) (dual of [224, 20, 88]-code), using
- concatenation of two codes [i] based on
  1. linear OA(16²³, 28, F₁₆, 21) (dual of [28, 5, 22]-code), using
    - discarding factors / shortening the dual code based on linear OA(16²³, 33, F₁₆, 21) (dual of [33, 10, 22]-code), using
      - extended algebraic-geometric code AG_e(F,11P) [i] based on function field F/F₁₆ with g(F) = 2 and N(F) ≥ 33, using
        a function field by SÃ©mirat [i]
  2. linear OA(2⁴, 8, F₂, 3) (dual of [8, 4, 4]-code or 8-cap in PG(3,2)), using
    - Reedâ€“Muller code RM(1,3) [i]
    - caps in base bÂ =Â 2 [i]
