concatenation of two codes [i] based on
1. linear OA(16²⁵, 31, F₁₆, 23) (dual of [31, 6, 24]-code), using
  - discarding factors / shortening the dual code based on linear OA(16²⁵, 33, F₁₆, 23) (dual of [33, 8, 24]-code), using
    - extended algebraic-geometric code AG_e(F,9P) [i] based on function field F/F₁₆ with g(F) = 2 and N(F) ≥ 33, using
      - a function field by SÃ©mirat [i]
