Information on Result #629608

Linear OA(2¹⁹⁹, 220, F₂, 77) (dual of [220, 21, 78]-code), using concatenation of two codes based on

linear OA(8⁴⁸, 55, F₈, 38) (dual of [55, 7, 39]-code), using
- discarding factors / shortening the dual code based on linear OA(8⁴⁸, 57, F₈, 38) (dual of [57, 9, 39]-code), using
  - 8 times truncation [i] based on linear OA(8⁵⁶, 65, F₈, 46) (dual of [65, 9, 47]-code), using
    - the BCH-code C(I) with length 65Â | 8⁴âˆ’1, defining interval IÂ =Â {5,12,19,…,−5}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 47 [i]
linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 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]
