Information on Result #571237

There is no linear OOA(3²¹⁶, 184, F₃, 3, 158) (dual of [(184, 3), 336, 159]-NRT-code), because 1 times depth reduction would yield linear OOA(3²¹⁶, 184, F₃, 2, 158) (dual of [(184, 2), 152, 159]-NRT-code), but

41 step m-reduction [i] would yield linear OA(3¹⁷⁵, 184, F₃, 117) (dual of [184, 9, 118]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(3¹⁷⁴, 180, F₃, 117) (dual of [180, 6, 118]-code), but
    - residual code [i] would yield linear OA(3⁵⁷, 62, F₃, 39) (dual of [62, 5, 40]-code), but
      - residual code [i] would yield linear OA(3¹⁸, 22, F₃, 13) (dual of [22, 4, 14]-code), but
        1 times truncation [i] would yield linear OA(3¹⁷, 21, F₃, 12) (dual of [21, 4, 13]-code), but
        â€œHNâ€ bound on codes from Brouwerâ€™s database [i]
  2. OA(3⁹, 184, S₃, 4), but
    - discarding factors would yield OA(3⁹, 100, S₃, 4), but
      - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 20001 > 3⁹ [i]

Mode: Bound (linear).
