(73−53, 73, 56851)-Net in Base 128 — Upper bound on s

There is no (20, 73, 56852)-net in base 128, because

1 times m-reduction [i] would yield (20, 72, 56852)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 52 382968 810993 273707 390830 055694 568361 465882 507254 212945 670096 105891 045167 223773 973144 843100 341780 071592 723270 026509 141050 603959 883236 079767 468853 654080 > 128⁷² [i]
