(146, 146+89, 120)-Net over F₂ — Digital

Digital (146, 235, 120)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(146, 146+89, 625)-Net in Base 2 — Upper bound on s

There is no (146, 235, 626)-net in base 2, because

1 times m-reduction [i] would yield (146, 234, 626)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 28261 196499 623258 168713 830463 527780 919452 899910 883332 735441 284779 887116 > 2²³⁴ [i]
