Linear OA(32⁸⁷, 1090, F₃₂, 35) (dual of [1090, 1003, 36]-code), using (u,Â u+v)-construction based on

linear OA(32²¹, 66, F₃₂, 17) (dual of [66, 45, 18]-code), using
- constructionÂ X applied to AG(F,45P) âŠ‚ AG(F,47P) [i] based on
  1. linear OA(32²⁰, 63, F₃₂, 17) (dual of [63, 43, 18]-code), using algebraic-geometric code AG(F,45P) [i] based on function field F/F₃₂ with g(F) = 3 and N(F) ≥ 64, using
    - a function field by SÃ©mirat [i]
  2. linear OA(32¹⁸, 63, F₃₂, 15) (dual of [63, 45, 16]-code), using algebraic-geometric code AG(F,47P) [i] based on function field F/F₃₂ with g(F) = 3 and N(F) ≥ 64 (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]
linear OA(32⁶⁶, 1024, F₃₂, 35) (dual of [1024, 958, 36]-code), using
