(182, 217, 4141522)-Net in Base 3 — Upper bound on s
There is no (182, 217, 4141523)-net in base 3, because
- 1 times m-reduction [i] would yield (182, 216, 4141523)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 11 433840 873338 067011 128140 117223 751249 536112 620995 900657 518109 138858 090169 634997 363533 880924 758437 568007 > 3216 [i]
