(114, 137, 1945071)-Net in Base 3 — Upper bound on s
There is no (114, 137, 1945072)-net in base 3, because
- 1 times m-reduction [i] would yield (114, 136, 1945072)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 77355 736563 772252 289369 984394 335298 092725 825466 698260 333813 401025 > 3136 [i]
