(146−45, 146, 130)-Net over F₂ — Digital

Digital (101, 146, 130)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(146−45, 146, 840)-Net in Base 2 — Upper bound on s

There is no (101, 146, 841)-net in base 2, because

1 times m-reduction [i] would yield (101, 145, 841)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 44 781903 405938 253030 743906 393396 840270 834928 > 2¹⁴⁵ [i]
