(115, 140, 889160)-Net in Base 3 — Upper bound on s
There is no (115, 140, 889161)-net in base 3, because
- 1 times m-reduction [i] would yield (115, 139, 889161)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 2 088599 905103 849849 682904 087889 142040 189970 868952 731891 638970 235313 > 3139 [i]
