Information on Result #2609634

There is no linear OOA(9¹³², 46, F₉, 3, 128) (dual of [(46, 3), 6, 129]-NRT-code), because 2 step truncation would yield linear OOA(9¹³⁰, 45, F₉, 3, 126) (dual of [(45, 3), 5, 127]-NRT-code), but

90 step m-reduction [i] would yield linear OA(9⁴⁰, 45, F₉, 36) (dual of [45, 5, 37]-code), but
- constructionÂ Y1 [i] would yield
  1. OA(9³⁹, 41, S₉, 36), but
    - the (dual) Plotkin bound shows that MÂ â‰¥ 739 044147 071729 616580 416051 031916 488005 / 37 > 9³⁹ [i]
  2. OA(9⁵, 45, S₉, 4), but
    - discarding factors would yield OA(9⁵, 44, S₉, 4), but
      - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 60897 > 9⁵ [i]

Mode: Bound (linear).
