(191−67, 191, 120)-Net over F₂ — Digital

Digital (124, 191, 120)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(191−67, 191, 664)-Net in Base 2 — Upper bound on s

There is no (124, 191, 665)-net in base 2, because

1 times m-reduction [i] would yield (124, 190, 665)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1597 751392 030065 611357 274051 997092 957230 189712 623180 780552 > 2¹⁹⁰ [i]
