(60−41, 60, 5321)-Net in Base 27 — Upper bound on s

There is no (19, 60, 5322)-net in base 27, because

1 times m-reduction [i] would yield (19, 59, 5322)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 2 828631 231429 696230 265603 907196 634897 364833 752591 922808 222383 795832 611753 375890 283081 > 27⁵⁹ [i]
