(25, 25+47, 3264)-Net in Base 16 — Upper bound on s

There is no (25, 72, 3265)-net in base 16, because

1 times m-reduction [i] would yield (25, 71, 3265)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 31 271670 468450 009027 199723 407997 087314 060433 461712 222496 460086 622154 831585 810822 346176 > 16⁷¹ [i]
