Information on Result #599923

There is no digital (3, 70, 148)-net over F₂₅, because extracting embedded orthogonal array would yield linear OA(25⁷⁰, 148, F₂₅, 67) (dual of [148, 78, 68]-code), but

constructionÂ Y1 [i] would yield
1. OA(25⁶⁹, 73, S₂₅, 67), but
  - the linear programming bound shows that MÂ â‰¥ 24178 564222 846123 668546 399721 917528 895562 151649 914153 732205 158997 548011 257094 913162 291049 957275 390625 / 7242 > 25⁶⁹ [i]
2. linear OA(25⁷⁸, 148, F₂₅, 75) (dual of [148, 70, 76]-code), but
  - discarding factors / shortening the dual code would yield linear OA(25⁷⁸, 103, F₂₅, 75) (dual of [103, 25, 76]-code), but
    - residual code [i] would yield OA(25³, 27, S₂₅, 3), but
      - bound for OAs with index unity [i]

Mode: Bound (linear).
