(50, 50+146, 65)-Net in Base 2 — Upper bound on s
There is no (50, 196, 66)-net in base 2, because
- 7 times m-reduction [i] would yield (50, 189, 66)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2189, 66, S2, 3, 139), but
- the LP bound with quadratic polynomials shows that M ≥ 29816 233243 086733 628219 999760 236415 476486 188361 204163 936256 / 35 > 2189 [i]
- extracting embedded OOA [i] would yield OOA(2189, 66, S2, 3, 139), but
