(139, 139+83, 118)-Net over F₂ — Digital

Digital (139, 222, 118)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(139, 139+83, 618)-Net in Base 2 — Upper bound on s

There is no (139, 222, 619)-net in base 2, because

1 times m-reduction [i] would yield (139, 221, 619)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 3 512271 966601 985720 828747 939593 247243 895080 082460 081470 894985 236780 > 2²²¹ [i]
