(97−55, 97, 3357)-Net in Base 9 — Upper bound on s

There is no (42, 97, 3358)-net in base 9, because

1 times m-reduction [i] would yield (42, 96, 3358)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 40 512146 460184 438077 803951 615047 931690 885936 978982 775968 663677 606729 506524 436184 253665 776913 > 9⁹⁶ [i]
