Information on Result #559641

There is no linear OOA(4¹⁰⁷, 92, F₄, 2, 86) (dual of [(92, 2), 77, 87]-NRT-code), because 22 step m-reduction 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).
