Linear OOA(81⁶¹, large, F₈₁, 2, 8), using 81¹ times duplication based on linear OOA(81⁶⁰, large, F₈₁, 2, 8), using

9 times NRT-code embedding in larger space [i] based on linear OOA(81⁴², 8388602, F₈₁, 2, 8) (dual of [(8388602, 2), 16777162, 9]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(81¹³, 4194301, F₈₁, 2, 4) (dual of [(4194301, 2), 8388589, 5]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(81¹³, 8388602, F₈₁, 4) (dual of [8388602, 8388589, 5]-code), using
      - discarding factors / shortening the dual code based on linear OA(81¹³, large, F₈₁, 4) (dual of [large, large−13, 5]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 21523360Â | 81⁴âˆ’1, defining interval IÂ =Â [0,3], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 5 [i]
