(197−71, 197, 115)-Net over F₂ — Digital

Digital (126, 197, 115)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(197−71, 197, 624)-Net in Base 2 — Upper bound on s

There is no (126, 197, 625)-net in base 2, because

1 times m-reduction [i] would yield (126, 196, 625)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 103956 116179 340280 627455 949558 729174 325099 702827 688658 016776 > 2¹⁹⁶ [i]
