(154−49, 154, 125)-Net over F₂ — Digital

Digital (105, 154, 125)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(154−49, 154, 778)-Net in Base 2 — Upper bound on s

There is no (105, 154, 779)-net in base 2, because

1 times m-reduction [i] would yield (105, 153, 779)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 11477 438290 977621 434269 759969 606803 612050 815472 > 2¹⁵³ [i]
