(104−17, 104, 2615742)-Net in Base 3 — Upper bound on s
There is no (87, 104, 2615743)-net in base 3, because
- 1 times m-reduction [i] would yield (87, 103, 2615743)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 13 915216 827431 423572 237744 702459 485015 680137 534449 > 3103 [i]
