(20, 20+97, 445)-Net in Base 9 — Upper bound on s
There is no (20, 117, 446)-net in base 9, because
- 1 times m-reduction [i] would yield (20, 116, 446)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 542 856267 714787 396566 855888 879329 135934 190634 134903 505278 458738 345964 518424 493762 728163 746040 858408 083112 294145 > 9116 [i]
