(157, 250, 132)-Net over F₂ — Digital

Digital (157, 250, 132)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(157, 250, 701)-Net in Base 2 — Upper bound on s

There is no (157, 250, 702)-net in base 2, because

1 times m-reduction [i] would yield (157, 249, 702)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 958 626428 099924 950309 288937 369819 851109 623114 376770 040257 440461 113276 665840 > 2²⁴⁹ [i]
