(84, 107, 97196)-Net in Base 3 — Upper bound on s
There is no (84, 107, 97197)-net in base 3, because
- 1 times m-reduction [i] would yield (84, 106, 97197)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 375 726411 802935 543415 588144 958126 393132 679399 527275 > 3106 [i]
