(128, 128+71, 119)-Net over F₂ — Digital

Digital (128, 199, 119)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(128, 128+71, 651)-Net in Base 2 — Upper bound on s

There is no (128, 199, 652)-net in base 2, because

1 times m-reduction [i] would yield (128, 198, 652)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 411352 236613 508610 213281 208293 250225 878895 780291 843897 503092 > 2¹⁹⁸ [i]
