Gilbertâ€“VarÅ¡amov bound [i]

(138, 211, 762)-Net in Base 2 — Upper bound on s

There is no (138, 211, 763)-net in base 2, because

1 times m-reduction [i] would yield (138, 210, 763)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1698 809431 116959 784136 522142 594507 768024 147483 580997 408478 501934 > 2²¹⁰ [i]
