Linear OA(32⁸¹, 1070, F₃₂, 33) (dual of [1070, 989, 34]-code), using (u,Â u+v)-construction based on

linear OA(32¹⁸, 46, F₃₂, 16) (dual of [46, 28, 17]-code), using
- constructionÂ X applied to AG(F,26P) âŠ‚ AG(F,28P) [i] based on
  1. linear OA(32¹⁷, 43, F₃₂, 16) (dual of [43, 26, 17]-code), using algebraic-geometric code AG(F,26P) [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(32¹⁵, 43, F₃₂, 14) (dual of [43, 28, 15]-code), using algebraic-geometric code AG(F,28P) [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]
linear OA(32⁶³, 1024, F₃₂, 33) (dual of [1024, 961, 34]-code), using
