(114, 114+25, 811371)-Net in Base 3 — Upper bound on s
There is no (114, 139, 811372)-net in base 3, because
- 1 times m-reduction [i] would yield (114, 138, 811372)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 696204 851096 846088 306364 413022 953295 258916 052900 719322 290285 767361 > 3138 [i]
