(27, 139, 600)-Net in Base 9 — Upper bound on s

There is no (27, 139, 601)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 4 733134 723014 676308 360539 084658 824418 396323 978094 909212 009435 332536 243908 485171 253198 752250 842101 691028 018119 314569 161884 806310 883521 > 9¹³⁹ [i]
