Information on Result #629523

Linear OA(2¹⁶², 216, F₂, 49) (dual of [216, 54, 50]-code), using concatenation of two codes based on

linear OA(8³⁶, 54, F₈, 24) (dual of [54, 18, 25]-code), using
- discarding factors / shortening the dual code based on linear OA(8³⁶, 61, F₈, 24) (dual of [61, 25, 25]-code), using
  - 4 times truncation [i] based on linear OA(8⁴⁰, 65, F₈, 28) (dual of [65, 25, 29]-code), using
    - the BCH-code C(I) with length 65Â | 8⁴âˆ’1, defining interval IÂ =Â {−8,−5,−2,…,8}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 29 [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]
