(247−93, 247, 127)-Net over F₂ — Digital

Digital (154, 247, 127)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(247−93, 247, 667)-Net in Base 2 — Upper bound on s

There is no (154, 247, 668)-net in base 2, because

1 times m-reduction [i] would yield (154, 246, 668)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 118 478924 627929 609931 115491 235619 571164 930889 424202 233104 542708 774224 581904 > 2²⁴⁶ [i]
