Information on Result #629471

Linear OA(2²³⁰, 240, F₂, 111) (dual of [240, 10, 112]-code), using concatenation of two codes based on

linear OA(4⁷⁵, 80, F₄, 55) (dual of [80, 5, 56]-code), using
- discarding factors / shortening the dual code based on linear OA(4⁷⁵, 81, F₄, 55) (dual of [81, 6, 56]-code), using
  - 4 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]
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]
