(198−103, 198, 642)-Net in Base 3 — Upper bound on s

There is no (95, 198, 643)-net in base 3, because

1 times m-reduction [i] would yield (95, 197, 643)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 10186 285389 462431 988403 755748 865250 739558 312066 097215 384285 101994 220593 722159 314782 616183 098443 > 3¹⁹⁷ [i]
