Linear OA(2³⁴, 48, F₂, 15) (dual of [48, 14, 16]-code), using concatenation of two codes based on

linear OA(4⁹, 16, F₄, 7) (dual of [16, 7, 8]-code), using
- discarding factors / shortening the dual code based on linear OA(4⁹, 17, F₄, 7) (dual of [17, 8, 8]-code), using
  - dual code (with bound on d by constructionÂ Y1) [i] based on
    1. linear OA(4⁸, 17, F₄, 6) (dual of [17, 9, 7]-code), using
      - the BCH-code C(I) with length 17Â | 4⁴âˆ’1, defining interval IÂ =Â {1,4,7,…,16}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 7 [i]
    2. nonexistence of linear OA(4⁷, 10, F₄, 6) (dual of [10, 3, 7]-code), because
      - bound for almost-MDS-codes with dimension nÂ =Â 3 [i]
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]
