Gilbertâ€“VarÅ¡amov bound [i]

(128, 128+63, 824)-Net in Base 2 — Upper bound on s

There is no (128, 191, 825)-net in base 2, because

1 times m-reduction [i] would yield (128, 190, 825)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1617 403800 139914 962798 034290 158261 160049 181525 128985 674624 > 2¹⁹⁰ [i]
