(179−63, 179, 113)-Net over F₂ — Digital

Digital (116, 179, 113)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(179−63, 179, 619)-Net in Base 2 — Upper bound on s

There is no (116, 179, 620)-net in base 2, because

1 times m-reduction [i] would yield (116, 178, 620)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 383972 234746 622283 809756 120751 194692 884090 205516 215960 > 2¹⁷⁸ [i]
