(189−126, 189, 93)-Net in Base 2 — Upper bound on s
There is no (63, 189, 94)-net in base 2, because
- 9 times m-reduction [i] would yield (63, 180, 94)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2180, 94, S2, 2, 117), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 98 079714 615416 886934 934209 737619 787751 599303 819750 539264 / 59 > 2180 [i]
- extracting embedded OOA [i] would yield OOA(2180, 94, S2, 2, 117), but
