There is no (32, 136, 134)-net in base 4, because

16 times m-reduction [i] would yield (32, 120, 134)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(4¹²⁰, 134, S₄, 88), but
  - the linear programming bound shows that MÂ â‰¥ 44879 226248 006156 277409 262412 286361 464349 961201 014006 795486 400435 014006 889500 377088 / 21749 419055 > 4¹²⁰ [i]
