linear OA(9¹⁹, 35, F₉, 13) (dual of [35, 16, 14]-code), using
- constructionÂ X applied to AG(F,9P) âŠ‚ AG(F,10P) [i] based on
  1. linear OA(9¹⁸, 32, F₉, 13) (dual of [32, 14, 14]-code), using algebraic-geometric code AG(F,9P) with degPÂ =Â 2 [i] based on function field F/F₉ with g(F) = 5 and N(F) ≥ 32, using a function field by SÃ©mirat [i]
  2. linear OA(9¹⁶, 32, F₉, 11) (dual of [32, 16, 12]-code), using algebraic-geometric code AG(F,10P) with degPÂ =Â 2 [i] based on function field F/F₉ with g(F) = 5 and N(F) ≥ 32 (see above)
  3. linear OA(9¹, 3, F₉, 1) (dual of [3, 2, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(9¹, s, F₉, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
