(128, 128+27, 1271814)-Net in Base 3 — Upper bound on s
There is no (128, 155, 1271815)-net in base 3, because
- 1 times m-reduction [i] would yield (128, 154, 1271815)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 29 969284 413300 820825 229859 682551 068816 016247 940753 164976 166053 773632 081207 > 3154 [i]
