(192−69, 192, 114)-Net over F₂ — Digital

Digital (123, 192, 114)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(192−69, 192, 615)-Net in Base 2 — Upper bound on s

There is no (123, 192, 616)-net in base 2, because

1 times m-reduction [i] would yield (123, 191, 616)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 3174 476614 624270 313021 364315 991772 810831 374452 980793 066195 > 2¹⁹¹ [i]
