There is no (32, 118, 135)-net in base 4, because

1 times m-reduction [i] would yield (32, 117, 135)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(4¹¹⁷, 135, S₄, 85), but
  - the linear programming bound shows that MÂ â‰¥ 45149 767227 503568 235754 222045 572597 718054 885690 811234 370829 340613 949495 422333 485056 / 1 479396 545045 > 4¹¹⁷ [i]
