6 times NRT-code embedding in larger space [i] based on linear OOA(81⁵⁸, 8388602, F₈₁, 2, 11) (dual of [(8388602, 2), 16777146, 12]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(81¹⁷, 4194301, F₈₁, 2, 5) (dual of [(4194301, 2), 8388585, 6]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(81¹⁷, 8388602, F₈₁, 5) (dual of [8388602, 8388585, 6]-code), using
      - discarding factors / shortening the dual code based on linear OA(81¹⁷, large, F₈₁, 5) (dual of [large, large−17, 6]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 21523361Â | 81⁸âˆ’1, defining interval IÂ =Â [0,2], and minimum distance dÂ â‰¥ |{−2,−1,0,1,2}|+1Â =Â 6 (BCH-bound) [i]
