(111, 111+57, 116)-Net over F₂ — Digital

Digital (111, 168, 116)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(111, 111+57, 664)-Net in Base 2 — Upper bound on s

There is no (111, 168, 665)-net in base 2, because

1 times m-reduction [i] would yield (111, 167, 665)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 187 234483 064921 301951 423233 262195 499455 349705 389648 > 2¹⁶⁷ [i]
