(242−124, 242, 1735)-Net in Base 4 — Upper bound on s

There is no (118, 242, 1736)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 51 232377 090061 853076 745073 970655 436285 571075 440487 712058 766817 163003 171810 060091 579163 941658 356878 901823 000537 854509 150795 418175 167968 721447 069448 > 4²⁴² [i]
