(171−57, 171, 122)-Net over F₂ — Digital

Digital (114, 171, 122)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(171−57, 171, 719)-Net in Base 2 — Upper bound on s

There is no (114, 171, 720)-net in base 2, because

1 times m-reduction [i] would yield (114, 170, 720)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1536 601833 430205 498311 686507 556652 656575 236196 158020 > 2¹⁷⁰ [i]
