linear OOA(8¹², 24, F₈, 2, 9) (dual of [(24, 2), 36, 10]-NRT-code), using
- extended algebraic-geometric NRT-code AG_e(2;F,38P) [i] based on function field F/F₈ with g(F) = 3 and N(F) ≥ 24, using
  - the Klein quartic over F₈ [i]
linear OOA(8⁸¹, 16386, F₈, 2, 19) (dual of [(16386, 2), 32691, 20]-NRT-code), using
- OOA 2-folding [i] based on linear OA(8⁸¹, 32772, F₈, 19) (dual of [32772, 32691, 20]-code), using
  - discarding factors / shortening the dual code based on linear OA(8⁸¹, 32773, F₈, 19) (dual of [32773, 32692, 20]-code), using
