linear OA(32¹³, 46, F₃₂, 11) (dual of [46, 33, 12]-code), using
- constructionÂ X applied to AG(F,31P) âŠ‚ AG(F,33P) [i] based on
  1. linear OA(32¹², 43, F₃₂, 11) (dual of [43, 31, 12]-code), using algebraic-geometric code AG(F,31P) [i] based on function field F/F₃₂ with g(F) = 1 and N(F) ≥ 44, using
    - a function field by SÃ©mirat [i]
  2. linear OA(32¹⁰, 43, F₃₂, 9) (dual of [43, 33, 10]-code), using algebraic-geometric code AG(F,33P) [i] based on function field F/F₃₂ with g(F) = 1 and N(F) ≥ 44 (see above)
  3. linear OA(32¹, 3, F₃₂, 1) (dual of [3, 2, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(32¹, s, F₃₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
