(102, 102+140, 1024)-Net in Base 4 — Upper bound on s

There is no (102, 242, 1025)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 50 950433 873739 002657 976977 888176 112785 410503 334535 795125 986427 619117 484726 816259 172951 674531 717145 481219 574637 414463 203200 684780 547883 965811 862016 > 4²⁴² [i]
