Information on Result #599337

There is no digital (3, 6, 154)-net over F₄, because extracting embedded orthogonal array would yield linear OA(4⁶, 154, F₄, 3) (dual of [154, 148, 4]-code or 154-cap in PG(5,4)), but

constructionÂ Y1 [i] would yield
1. 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. linear OA(4¹⁴⁸, 154, F₄, 112) (dual of [154, 6, 113]-code), but
  - discarding factors / shortening the dual code would yield linear OA(4¹⁴⁸, 153, F₄, 112) (dual of [153, 5, 113]-code), but
    - residual code [i] would yield linear OA(4³⁶, 40, F₄, 28) (dual of [40, 4, 29]-code), but
      - residual code [i] would yield linear OA(4⁸, 11, F₄, 7) (dual of [11, 3, 8]-code), but
