OOA(128⁶⁸, 5625042, S₁₂₈, 3, 13), using discarding parts of the base based on linear OOA(256⁵⁹, 5625042, F₂₅₆, 3, 13) (dual of [(5625042, 3), 16875067, 14]-NRT-code), using

generalized (u,Â u+v)-construction [i] based on
1. linear OOA(256⁶, 32640, F₂₅₆, 3, 4) (dual of [(32640, 3), 97914, 5]-NRT-code), using
  - OA 2-folding and stacking [i] based on linear OA(256⁶, 65280, F₂₅₆, 4) (dual of [65280, 65274, 5]-code), using
    - 1 times truncation [i] based on linear OA(256⁷, 65281, F₂₅₆, 5) (dual of [65281, 65274, 6]-code), using
      - a code by Danev and Olsson [i]
2. linear OOA(256¹⁶, 2796201, F₂₅₆, 3, 6) (dual of [(2796201, 3), 8388587, 7]-NRT-code), using
  - OOA 3-folding [i] based on linear OA(256¹⁶, large, F₂₅₆, 6) (dual of [large, large−16, 7]-code), using
    - the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 256³âˆ’1, defining interval IÂ =Â [0,5], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 7 [i]
