(138−108, 138, 686)-Net in Base 9 — Upper bound on s

There is no (30, 138, 687)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 493513 915468 362639 942161 188516 430968 135435 574809 730261 308583 067674 879562 174248 679530 886841 463115 669873 079851 380975 589750 079843 773777 > 9¹³⁸ [i]
