(139−102, 139, 958)-Net in Base 9 — Upper bound on s

There is no (37, 139, 959)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 4 429050 791445 564230 616399 049668 081655 031439 587330 217115 397448 304111 205721 532946 462932 602582 642978 199309 843793 001021 086536 450340 229225 > 9¹³⁹ [i]
