Gilbertâ€“VarÅ¡amov bound [i]

(128, 128+73, 619)-Net in Base 2 — Upper bound on s

There is no (128, 201, 620)-net in base 2, because

1 times m-reduction [i] would yield (128, 200, 620)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1 607623 822701 315975 771575 963498 823750 493616 805845 194374 265854 > 2²⁰⁰ [i]
