(90, 90+29, 31746)-Net in Base 3 — Upper bound on s
There is no (90, 119, 31747)-net in base 3, because
- 1 times m-reduction [i] would yield (90, 118, 31747)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 199 725611 087183 114783 809281 217593 194716 843901 884449 694797 > 3118 [i]
