(192, 235, 19594)-Net in Base 2 — Upper bound on s

There is no (192, 235, 19595)-net in base 2, because

1 times m-reduction [i] would yield (192, 234, 19595)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 27612 987984 851402 584603 613783 386431 939263 181887 549978 473355 136942 589952 > 2²³⁴ [i]
