(118, 155, 45600)-Net in Base 3 — Upper bound on s
There is no (118, 155, 45601)-net in base 3, because
- 1 times m-reduction [i] would yield (118, 154, 45601)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 29 973429 547031 845560 230384 015084 657555 721207 885032 316523 675889 336486 584969 > 3154 [i]
