(69, 96, 6662333)-Net in Base 9 — Upper bound on s
There is no (69, 96, 6662334)-net in base 9, because
- 1 times m-reduction [i] would yield (69, 95, 6662334)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 4 498204 459328 716459 767003 342301 508309 470788 817048 284301 027830 819354 431853 203243 064028 213425 > 995 [i]
