(91, 116, 98785)-Net in Base 3 — Upper bound on s
There is no (91, 116, 98786)-net in base 3, because
- 1 times m-reduction [i] would yield (91, 115, 98786)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 7 395617 081594 677552 682380 623223 098606 651363 960599 489913 > 3115 [i]
