(21, 21+125, 111)-Net in Base 5 — Upper bound on s
There is no (21, 146, 112)-net in base 5, because
- 49 times m-reduction [i] would yield (21, 97, 112)-net in base 5, but
- extracting embedded orthogonal array [i] would yield OA(597, 112, S5, 76), but
- the linear programming bound shows that M ≥ 29 282971 382900 591824 936232 851882 769051 034272 056455 165511 579252 779483 795166 015625 / 409917 357801 > 597 [i]
- extracting embedded orthogonal array [i] would yield OA(597, 112, S5, 76), but
