(140−88, 140, 2317)-Net in Base 9 — Upper bound on s

There is no (52, 140, 2318)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 39 528130 375747 868103 865348 358022 827641 460965 612872 318608 136309 070780 767629 169239 706683 909143 208195 478790 293679 303684 368434 893671 134145 > 9¹⁴⁰ [i]
