Linear OOA(25⁹⁷, large, F₂₅, 2, 10), using 15 times NRT-code embedding in larger space based on linear OOA(25⁶⁷, 8388602, F₂₅, 2, 10) (dual of [(8388602, 2), 16777137, 11]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(25²¹, 4194301, F₂₅, 2, 5) (dual of [(4194301, 2), 8388581, 6]-NRT-code), using
  - OOA 2-folding [i] based on linear OA(25²¹, 8388602, F₂₅, 5) (dual of [8388602, 8388581, 6]-code), using
    - discarding factors / shortening the dual code based on linear OA(25²¹, large, F₂₅, 5) (dual of [large, large−21, 6]-code), using
      - the expurgated narrow-sense BCH-code C(I) with length 9765626Â | 25¹⁰âˆ’1, defining interval IÂ =Â [0,2], and minimum distance dÂ â‰¥ |{−2,−1,0,1,2}|+1Â =Â 6 (BCH-bound) [i]
