Linear OOA(27⁸⁹, large, F₂₇, 2, 12), using 27¹ times duplication based on linear OOA(27⁸⁸, large, F₂₇, 2, 12), using

3 times NRT-code embedding in larger space [i] based on linear OOA(27⁸², 8388602, F₂₇, 2, 12) (dual of [(8388602, 2), 16777122, 13]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(27²⁶, 4194301, F₂₇, 2, 6) (dual of [(4194301, 2), 8388576, 7]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(27²⁶, 8388602, F₂₇, 6) (dual of [8388602, 8388576, 7]-code), using
      - discarding factors / shortening the dual code based on linear OA(27²⁶, large, F₂₇, 6) (dual of [large, large−26, 7]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 14348906Â = 27⁵âˆ’1, defining interval IÂ =Â [0,5], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 7 [i]
