Information on Result #631110

Linear OA(3²⁴⁹, 261, F₃, 135) (dual of [261, 12, 136]-code), using concatenation of two codes based on

linear OA(9⁸¹, 87, F₉, 67) (dual of [87, 6, 68]-code), using
- discarding factors / shortening the dual code based on linear OA(9⁸¹, 88, F₉, 67) (dual of [88, 7, 68]-code), using
  - 3 times truncation [i] based on linear OA(9⁸⁴, 91, F₉, 70) (dual of [91, 7, 71]-code), using
    - the BCH-code C(I) with length 91Â | 9³âˆ’1, defining interval IÂ =Â {−9,15,39,…,9}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 71 [i]
linear OA(3¹, 3, F₃, 1) (dual of [3, 2, 2]-code), using
- discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
  - parity-check code [i]
