(43, 43+19, 1521611)-Net in Base 9 — Upper bound on s
There is no (43, 62, 1521612)-net in base 9, because
- 1 times m-reduction [i] would yield (43, 61, 1521612)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 16173 176885 057480 104552 847175 640177 721117 088243 536419 262305 > 961 [i]
