Linear OA(2²³³, 245, F₂, 110) (dual of [245, 12, 111]-code), using 7 times truncation 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]
