Linear OA(2¹⁹⁴, 246, F₂, 65) (dual of [246, 52, 66]-code), using 2 times truncation based on linear OA(2¹⁹⁶, 248, F₂, 67) (dual of [248, 52, 68]-code), using

concatenation of two codes [i] based on
1. linear OA(16¹⁸, 31, F₁₆, 16) (dual of [31, 13, 17]-code), using
  - discarding factors / shortening the dual code based on linear OA(16¹⁸, 33, F₁₆, 16) (dual of [33, 15, 17]-code), using
    - extended algebraic-geometric code AG_e(F,16P) [i] based on function field F/F₁₆ with g(F) = 2 and N(F) ≥ 33, using
      - a function field by SÃ©mirat [i]
