Gilbertâ€“VarÅ¡amov bound [i]

(160, 257, 687)-Net in Base 2 — Upper bound on s

There is no (160, 257, 688)-net in base 2, because

1 times m-reduction [i] would yield (160, 256, 688)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 123163 282409 881444 299764 924401 860059 294898 311527 091855 123904 229553 446009 364568 > 2²⁵⁶ [i]
