(140−102, 140, 1002)-Net in Base 9 — Upper bound on s

There is no (38, 140, 1003)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 40 704062 416648 515568 358991 281569 152615 563935 182472 877838 893775 006553 934131 831192 427134 742816 502667 687910 530391 037290 778078 027409 929225 > 9¹⁴⁰ [i]
