(114, 141, 389575)-Net in Base 3 — Upper bound on s
There is no (114, 141, 389576)-net in base 3, because
- 1 times m-reduction [i] would yield (114, 140, 389576)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 6 265984 244806 503254 644311 502786 107442 104126 738991 132168 902809 040273 > 3140 [i]
