Gilbertâ€“VarÅ¡amov bound [i]

(139, 214, 738)-Net in Base 2 — Upper bound on s

There is no (139, 214, 739)-net in base 2, because

1 times m-reduction [i] would yield (139, 213, 739)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 13198 097666 721400 888750 225800 993310 394640 091889 758756 136406 833712 > 2²¹³ [i]
