(98, 98+21, 965990)-Net in Base 3 — Upper bound on s
There is no (98, 119, 965991)-net in base 3, because
- 1 times m-reduction [i] would yield (98, 118, 965991)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 199 668904 727082 944166 622476 608128 543485 179755 639397 241917 > 3118 [i]
