(135, 135+27, 2297931)-Net in Base 3 — Upper bound on s
There is no (135, 162, 2297932)-net in base 3, because
- 1 times m-reduction [i] would yield (135, 161, 2297932)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 65542 588212 041740 990529 264936 372200 380783 703475 182168 539526 728780 018583 608441 > 3161 [i]
