Linear OOA(256⁶³, large, F₂₅₆, 2, 14), using 2 times NRT-code embedding in larger space based on linear OOA(256⁵⁹, 8388602, F₂₅₆, 2, 14) (dual of [(8388602, 2), 16777145, 15]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(256¹⁹, 4194301, F₂₅₆, 2, 7) (dual of [(4194301, 2), 8388583, 8]-NRT-code), using
  - OOA 2-folding [i] based on linear OA(256¹⁹, 8388602, F₂₅₆, 7) (dual of [8388602, 8388583, 8]-code), using
    - discarding factors / shortening the dual code based on linear OA(256¹⁹, large, F₂₅₆, 7) (dual of [large, large−19, 8]-code), using
      - the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 256³âˆ’1, defining interval IÂ =Â [0,6], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 8 [i]
