(85, 118, 8078794)-Net in Base 9 — Upper bound on s
There is no (85, 118, 8078795)-net in base 9, because
- 1 times m-reduction [i] would yield (85, 117, 8078795)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 4429 694519 806134 002521 736661 647842 213724 166395 018050 911928 912044 194258 672912 194951 152358 913539 889136 641776 116097 > 9117 [i]
