(199−35, 199, 1294103)-Net in Base 3 — Upper bound on s

There is no (164, 199, 1294104)-net in base 3, because

1 times m-reduction [i] would yield (164, 198, 1294104)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 29512 880363 296021 899566 165755 092365 609991 287926 614543 516955 570982 734071 609960 711274 753442 366769 > 3¹⁹⁸ [i]
