(118−59, 118, 463)-Net in Base 3 — Upper bound on s

There is no (59, 118, 464)-net in base 3, because

1 times m-reduction [i] would yield (59, 117, 464)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 70 145043 554945 794520 040194 956781 859287 810867 830014 501537 > 3¹¹⁷ [i]
