Linear OOA(8⁸³, large, F₈, 3, 7), using strength reduction based on linear OOA(8⁸³, large, F₈, 3, 8), using

(u,Â u+v)-construction [i] based on
1. linear OOA(8²⁵, 4194301, F₈, 3, 4) (dual of [(4194301, 3), 12582878, 5]-NRT-code), using
  - OA 2-folding and stacking [i] based on linear OA(8²⁵, 8388602, F₈, 4) (dual of [8388602, 8388577, 5]-code), using
    - discarding factors / shortening the dual code based on linear OA(8²⁵, large, F₈, 4) (dual of [large, large−25, 5]-code), using
      - the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 8⁸âˆ’1, defining interval IÂ =Â [0,3], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 5 [i]
2. linear OOA(8⁵⁸, 5592402, F₈, 3, 8) (dual of [(5592402, 3), 16777148, 9]-NRT-code), using
  - trace code [i] based on linear OOA(64²⁹, 2796201, F₆₄, 3, 8) (dual of [(2796201, 3), 8388574, 9]-NRT-code), using
    - OOA 3-folding [i] based on linear OA(64²⁹, large, F₆₄, 8) (dual of [large, large−29, 9]-code), using
      - the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 64⁴âˆ’1, defining interval IÂ =Â [0,7], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 9 [i]
