Linear OOA(2²³⁸, 50, F₂, 5, 115) (dual of [(50, 5), 12, 116]-NRT-code), using OOA 5-folding based on linear OA(2²³⁸, 250, F₂, 115) (dual of [250, 12, 116]-code), using

2 times truncation [i] based on linear OA(2²⁴⁰, 252, F₂, 117) (dual of [252, 12, 118]-code), using
- concatenation of two codes [i] based on
  1. linear OA(4⁷⁸, 84, F₄, 58) (dual of [84, 6, 59]-code), using
    - 1 times truncation [i] based on linear OA(4⁷⁹, 85, F₄, 59) (dual of [85, 6, 60]-code), using
      - the BCH-code C(I) with length 85Â | 4⁴âˆ’1, defining interval IÂ =Â {−4,2,8,…,4}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 60 [i]
  2. linear OA(2¹, 3, F₂, 1) (dual of [3, 2, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
