(38, 38+55, 31657)-Net in Base 27 — Upper bound on s

There is no (38, 93, 31658)-net in base 27, because

1 times m-reduction [i] would yield (38, 92, 31658)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 484785 388395 612168 865046 746391 199833 309353 468733 434308 065463 328924 743313 760510 075778 022415 840909 605547 096267 213994 255983 036441 385649 > 27⁹² [i]
