(74, 74+56, 38030)-Net in Base 9 — Upper bound on s

There is no (74, 130, 38031)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 11263 397606 610281 192276 750164 099886 248710 557829 489095 725904 646569 969914 080317 262177 538275 358789 028027 251665 964387 852022 524193 > 9¹³⁰ [i]
