Gilbertâ€“VarÅ¡amov bound [i]

(154, 249, 645)-Net in Base 2 — Upper bound on s

There is no (154, 249, 646)-net in base 2, because

1 times m-reduction [i] would yield (154, 248, 646)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 481 844720 561024 220982 104668 255346 024201 380035 837323 635889 550422 535361 170048 > 2²⁴⁸ [i]
