(74−47, 74, 12650)-Net in Base 27 — Upper bound on s

There is no (27, 74, 12651)-net in base 27, because

1 times m-reduction [i] would yield (27, 73, 12651)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 309 130257 601158 872753 146795 761667 719502 036875 074260 085855 703744 057963 366688 528534 820773 035906 387203 576763 > 27⁷³ [i]
