(56, 56+84, 3104)-Net in Base 9 — Upper bound on s

There is no (56, 140, 3105)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 39 716662 170578 250636 947380 887460 988066 843158 218431 152294 380908 955271 895129 585972 641875 099751 433344 058826 485001 001883 098125 694129 893009 > 9¹⁴⁰ [i]
