Information on Result #573019

There is no linear OOA(4⁹¹, 92, F₄, 3, 70) (dual of [(92, 3), 185, 71]-NRT-code), because 1 times depth reduction would yield linear OOA(4⁹¹, 92, F₄, 2, 70) (dual of [(92, 2), 93, 71]-NRT-code), but

6 step m-reduction [i] would yield linear OA(4⁸⁵, 92, F₄, 64) (dual of [92, 7, 65]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(4⁸⁴, 88, F₄, 64) (dual of [88, 4, 65]-code), but
    - Griesmer bound [i]
  2. OA(4⁷, 92, S₄, 4), but
    - discarding factors would yield OA(4⁷, 61, S₄, 4), but
      - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 16654 > 4⁷ [i]

Mode: Bound (linear).
