Linear OOA(64⁷¹, large, F₆₄, 2, 10), using 64¹ times duplication based on linear OOA(64⁷⁰, large, F₆₄, 2, 10), using

8 times NRT-code embedding in larger space [i] based on linear OOA(64⁵⁴, 8388602, F₆₄, 2, 10) (dual of [(8388602, 2), 16777150, 11]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(64¹⁷, 4194301, F₆₄, 2, 5) (dual of [(4194301, 2), 8388585, 6]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(64¹⁷, 8388602, F₆₄, 5) (dual of [8388602, 8388585, 6]-code), using
      - discarding factors / shortening the dual code based on linear OA(64¹⁷, large, F₆₄, 5) (dual of [large, large−17, 6]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 16777217Â | 64⁸âˆ’1, defining interval IÂ =Â [0,2], and minimum distance dÂ â‰¥ |{−2,−1,0,1,2}|+1Â =Â 6 (BCH-bound) [i]
  2. linear OOA(64³⁷, 4194301, F₆₄, 2, 10) (dual of [(4194301, 2), 8388565, 11]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(64³⁷, 8388602, F₆₄, 10) (dual of [8388602, 8388565, 11]-code), using
      - discarding factors / shortening the dual code based on linear OA(64³⁷, large, F₆₄, 10) (dual of [large, large−37, 11]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 64⁴âˆ’1, defining interval IÂ =Â [0,9], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]
