Linear OOA(25¹⁰⁹, large, F₂₅, 2, 14), using 6 times NRT-code embedding in larger space based on linear OOA(25⁹⁷, 8388602, F₂₅, 2, 14) (dual of [(8388602, 2), 16777107, 15]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(25³¹, 4194301, F₂₅, 2, 7) (dual of [(4194301, 2), 8388571, 8]-NRT-code), using
  - OOA 2-folding [i] based on linear OA(25³¹, 8388602, F₂₅, 7) (dual of [8388602, 8388571, 8]-code), using
    - discarding factors / shortening the dual code based on linear OA(25³¹, large, F₂₅, 7) (dual of [large, large−31, 8]-code), using
      - the expurgated narrow-sense BCH-code C(I) with length 9765626Â | 25¹⁰âˆ’1, defining interval IÂ =Â [0,3], and minimum distance dÂ â‰¥ |{−3,−2,…,3}|+1Â =Â 8 (BCH-bound) [i]
