(120, 120+122, 861)-Net in Base 3 — Upper bound on s

There is no (120, 242, 862)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 29 806899 018755 886862 999945 556423 356743 523891 002536 246177 685990 978482 018366 690930 666652 311099 116665 134907 903970 173285 > 3²⁴² [i]
