(137, 216, 121)-Net over F₂ — Digital

Digital (137, 216, 121)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(137, 216, 647)-Net in Base 2 — Upper bound on s

There is no (137, 216, 648)-net in base 2, because

1 times m-reduction [i] would yield (137, 215, 648)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 55399 578548 114811 499848 821486 710112 369765 972316 821023 118749 700308 > 2²¹⁵ [i]
