(99−15, 99, 8083247)-Net in Base 3 — Upper bound on s
There is no (84, 99, 8083248)-net in base 3, because
- 1 times m-reduction [i] would yield (84, 98, 8083248)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 57264 200566 368126 152924 533115 403952 778484 654657 > 398 [i]
