Gilbertâ€“VarÅ¡amov bound [i]

(239−87, 239, 721)-Net in Base 2 — Upper bound on s

There is no (152, 239, 722)-net in base 2, because

1 times m-reduction [i] would yield (152, 238, 722)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 465053 773744 872340 872265 094075 589648 812869 228694 587660 501399 483206 696000 > 2²³⁸ [i]
