(134−21, 134, 5019473)-Net in Base 3 — Upper bound on s
There is no (113, 134, 5019474)-net in base 3, because
- 1 times m-reduction [i] would yield (113, 133, 5019474)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 2865 017198 648052 575897 338919 662313 894031 710177 519534 948736 559301 > 3133 [i]
