Linear OA(2²²⁷, 284, F₂, 69) (dual of [284, 57, 70]-code), using concatenation of two codes based on

linear OA(8⁵², 71, F₈, 34) (dual of [71, 19, 35]-code), using
- discarding factors / shortening the dual code based on linear OA(8⁵², 73, F₈, 34) (dual of [73, 21, 35]-code), using
  - constructionÂ X applied to AG(F,29P) âŠ‚ AG(F,34P) [i] based on
    1. linear OA(8⁴⁸, 64, F₈, 34) (dual of [64, 16, 35]-code), using algebraic-geometric code AG(F,29P) [i] based on function field F/F₈ with g(F) = 14 and N(F) ≥ 65, using
      - the Suzuki function field over F₈ [i]
    2. linear OA(8⁴³, 64, F₈, 29) (dual of [64, 21, 30]-code), using algebraic-geometric code AG(F,34P) [i] based on function field F/F₈ with g(F) = 14 and N(F) ≥ 65 (see above)
    3. linear OA(8⁴, 9, F₈, 4) (dual of [9, 5, 5]-code or 9-arc in PG(3,8)), using
      - extended Reedâ€“Solomon code RS_e(5,8) [i]
linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 2]-code), using
