Digital (148, 218, 164)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(218−70, 218, 992)-Net in Base 2 — Upper bound on s

There is no (148, 218, 993)-net in base 2, because

the generalized Rao bound for nets shows that 2^mÂ â‰¥ 434544 557583 102289 886130 361602 341847 714682 615152 719367 525314 099864 > 2²¹⁸ [i]
