Linear OOA(64⁸⁸, large, F₆₄, 2, 15), using 3 times NRT-code embedding in larger space based on linear OOA(64⁸², 8388602, F₆₄, 2, 15) (dual of [(8388602, 2), 16777122, 16]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(64²⁵, 4194301, F₆₄, 2, 7) (dual of [(4194301, 2), 8388577, 8]-NRT-code), using
  - OOA 2-folding [i] based on linear OA(64²⁵, 8388602, F₆₄, 7) (dual of [8388602, 8388577, 8]-code), using
    - discarding factors / shortening the dual code based on linear OA(64²⁵, large, F₆₄, 7) (dual of [large, large−25, 8]-code), using
      - the expurgated narrow-sense BCH-code C(I) with length 16777217Â | 64⁸âˆ’1, defining interval IÂ =Â [0,3], and minimum distance dÂ â‰¥ |{−3,−2,…,3}|+1Â =Â 8 (BCH-bound) [i]
