(151, 238, 131)-Net over F₂ — Digital

Digital (151, 238, 131)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(151, 238, 708)-Net in Base 2 — Upper bound on s

There is no (151, 238, 709)-net in base 2, because

1 times m-reduction [i] would yield (151, 237, 709)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 226067 081799 696326 838794 467704 460340 024311 634616 206014 807134 038197 634560 > 2²³⁷ [i]
