Linear OOA(27⁸³, large, F₂₇, 2, 5), using 27¹ times duplication based on linear OOA(27⁸², large, F₂₇, 2, 5), using

27 times NRT-code embedding in larger space [i] based on linear OOA(27²⁸, large, F₂₇, 2, 5), using
- generalized (u,Â u+v)-construction [i] based on
  1. linear OOA(27¹, 4194301, F₂₇, 2, 1) (dual of [(4194301, 2), 8388601, 2]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(27¹, s, F₂₇, 2, 1) for arbitrarily large s, using
      - appending 1 arbitrary column [i] based on linear OA(27¹, s, F₂₇, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
        parity-check code [i]
  2. linear OOA(27⁶, 4194301, F₂₇, 2, 2) (dual of [(4194301, 2), 8388596, 3]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(27⁶, large, F₂₇, 2, 2), using
      - appending kth column [i] based on linear OA(27⁶, large, F₂₇, 2) (dual of [large, large−6, 3]-code), using
        Hamming code H(6,27) [i]
  3. linear OOA(27²¹, 4194301, F₂₇, 2, 5) (dual of [(4194301, 2), 8388581, 6]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(27²¹, 8388602, F₂₇, 5) (dual of [8388602, 8388581, 6]-code), using
      - discarding factors / shortening the dual code based on linear OA(27²¹, large, F₂₇, 5) (dual of [large, large−21, 6]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 14348908Â | 27¹⁰âˆ’1, defining interval IÂ =Â [0,2], and minimum distance dÂ â‰¥ |{−2,−1,0,1,2}|+1Â =Â 6 (BCH-bound) [i]
