(103, 122, 5387049)-Net in Base 3 — Upper bound on s
There is no (103, 122, 5387050)-net in base 3, because
- 1 times m-reduction [i] would yield (103, 121, 5387050)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 5391 035028 354727 627795 545414 348598 054533 075713 948575 218821 > 3121 [i]
