(139, 139+56, 58699)-Net in Base 4 — Upper bound on s

There is no (139, 195, 58700)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2522 607327 766774 199109 300438 542434 224074 891741 080316 853451 414162 194115 520205 341216 698400 829830 502547 646953 799444 197840 > 4¹⁹⁵ [i]
