(64, 192, 475)-Net in Base 4 — Upper bound on s

There is no (64, 192, 476)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 42 024518 712052 116028 285841 319577 751986 718235 958246 391543 858771 835157 260625 542147 683174 727134 146484 624199 279501 888631 > 4¹⁹² [i]
