Information on Result #578154

There is no linear OOA(8¹¹⁸, 41, F₈, 3, 114) (dual of [(41, 3), 5, 115]-NRT-code), because 82 step m-reduction would yield linear OA(8³⁶, 41, F₈, 32) (dual of [41, 5, 33]-code), but

constructionÂ Y1 [i] would yield
1. OA(8³⁵, 37, S₈, 32), but
  - the (dual) Plotkin bound shows that MÂ â‰¥ 1622 592768 292133 633915 780102 881280 / 33 > 8³⁵ [i]
2. OA(8⁵, 41, S₈, 4), but
  - discarding factors would yield OA(8⁵, 37, S₈, 4), but
    - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 32894 > 8⁵ [i]

Mode: Bound (linear).
