Digital (119, 182, 119)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(182−63, 182, 665)-Net in Base 2 — Upper bound on s

There is no (119, 182, 666)-net in base 2, because

1 times m-reduction [i] would yield (119, 181, 666)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 3 068846 107785 377941 897636 893761 559119 114681 787461 500160 > 2¹⁸¹ [i]
