(242−128, 242, 1502)-Net in Base 4 — Upper bound on s

There is no (114, 242, 1503)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 50 809541 663304 339229 754416 620879 835618 537871 180206 587013 496127 687181 319458 601330 779402 339934 598248 223232 246753 678747 754512 295889 242884 265282 383831 > 4²⁴² [i]
