(237−190, 237, 58)-Net in Base 2 — Upper bound on s
There is no (47, 237, 59)-net in base 2, because
- 11 times m-reduction [i] would yield (47, 226, 59)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2226, 59, S2, 4, 179), but
- the LP bound with quadratic polynomials shows that M ≥ 5445 909226 764429 238522 737047 577965 396074 703173 353195 641182 929270 341632 / 45 > 2226 [i]
- extracting embedded OOA [i] would yield OOA(2226, 59, S2, 4, 179), but
