(153−25, 153, 34370)-Net in Base 2 — Upper bound on s
There is no (128, 153, 34371)-net in base 2, because
- 1 times m-reduction [i] would yield (128, 152, 34371)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 5709 804253 945994 499715 797814 917315 407672 612464 > 2152 [i]
