Digital (121, 180, 133)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(121, 121+59, 799)-Net in Base 2 — Upper bound on s

There is no (121, 180, 800)-net in base 2, because

1 times m-reduction [i] would yield (121, 179, 800)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 772437 873991 950687 253680 486335 170333 857897 853284 835583 > 2¹⁷⁹ [i]
