(70, 70+122, 567)-Net in Base 4 — Upper bound on s

There is no (70, 192, 568)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 39 711984 741136 524809 011865 719514 321189 619077 065473 959820 991155 917937 870475 751761 111781 144053 155388 934035 171783 147840 > 4¹⁹² [i]
