(122, 191, 112)-Net over F₂ — Digital

Digital (122, 191, 112)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(122, 191, 602)-Net in Base 2 — Upper bound on s

There is no (122, 191, 603)-net in base 2, because

1 times m-reduction [i] would yield (122, 190, 603)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1619 354936 004886 816668 248490 203127 436676 839040 948449 081578 > 2¹⁹⁰ [i]
