Information on Result #3147095

There is no digital (11, 44, 55)-net over F₄, because 1 times m-reduction would yield digital (11, 43, 55)-net over F₄, but

extracting embedded orthogonal array [i] would yield linear OA(4⁴³, 55, F₄, 32) (dual of [55, 12, 33]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(4⁴², 47, F₄, 32) (dual of [47, 5, 33]-code), but
    - constructionÂ Y1 [i] would yield
      1. linear OA(4⁴¹, 44, F₄, 32) (dual of [44, 3, 33]-code), but
        Griesmer bound [i]
      2. linear OA(4⁵, 47, F₄, 3) (dual of [47, 42, 4]-code or 47-cap in PG(4,4)), but
        discarding factors / shortening the dual code would yield linear OA(4⁵, 42, F₄, 3) (dual of [42, 37, 4]-code or 42-cap in PG(4,4)), but
        41 is the largest size of a cap in PG(4,Â 4) [i]
  2. OA(4¹², 55, S₄, 8), but
    - discarding factors would yield OA(4¹², 49, S₄, 8), but
      - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 17 670136 > 4¹² [i]
