(158−132, 158, 111)-Net in Base 4 — Upper bound on s
There is no (26, 158, 112)-net in base 4, because
- 60 times m-reduction [i] would yield (26, 98, 112)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(498, 112, S4, 72), but
- the linear programming bound shows that M ≥ 1 166662 731140 735083 887873 150433 161508 032759 728734 208123 114163 798016 / 9 452405 > 498 [i]
- extracting embedded orthogonal array [i] would yield OA(498, 112, S4, 72), but
