(84, 127, 576564)-Net in Base 9 — Upper bound on s
There is no (84, 127, 576565)-net in base 9, because
- 1 times m-reduction [i] would yield (84, 126, 576565)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 1 716166 012464 197257 927097 093086 136212 757322 408804 840021 733271 344542 009324 663100 201867 823025 817908 794297 476168 384693 872201 > 9126 [i]
