Linear OOA(25¹⁰⁸, large, F₂₅, 2, 14), using 25¹ times duplication based on linear OOA(25¹⁰⁷, large, F₂₅, 2, 14), using

5 times NRT-code embedding in larger space [i] 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]
  2. linear OOA(25⁶⁶, 4194301, F₂₅, 2, 14) (dual of [(4194301, 2), 8388536, 15]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(25⁶⁶, 8388602, F₂₅, 14) (dual of [8388602, 8388536, 15]-code), using
      - discarding factors / shortening the dual code based on linear OA(25⁶⁶, large, F₂₅, 14) (dual of [large, large−66, 15]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 9765624Â = 25⁵âˆ’1, defining interval IÂ =Â [0,13], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 15 [i]
