(120, 120+118, 1992)-Net in Base 4 — Upper bound on s
There is no (120, 238, 1993)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 195766 871957 355615 912174 128968 759135 666122 481913 191500 258483 719994 045005 570992 330327 011415 179889 158876 530923 165582 799115 946496 902389 450471 531328 > 4238 [i]
