(220−83, 220, 114)-Net over F₂ — Digital

Digital (137, 220, 114)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(220−83, 220, 595)-Net in Base 2 — Upper bound on s

There is no (137, 220, 596)-net in base 2, because

1 times m-reduction [i] would yield (137, 219, 596)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 848235 690014 989694 874435 171060 539986 344061 754180 563935 208299 736500 > 2²¹⁹ [i]
