(120−31, 120, 19569)-Net in Base 3 — Upper bound on s
There is no (89, 120, 19570)-net in base 3, because
- 1 times m-reduction [i] would yield (89, 119, 19570)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 599 288788 692021 636769 855849 359122 815413 644223 847944 935385 > 3119 [i]
