(153−29, 153, 11194)-Net in Base 2 — Upper bound on s
There is no (124, 153, 11195)-net in base 2, because
- 1 times m-reduction [i] would yield (124, 152, 11195)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 5715 357791 269759 856534 485564 120057 169907 811164 > 2152 [i]
