(19, 56, 6857)-Net in Base 27 — Upper bound on s

There is no (19, 56, 6858)-net in base 27, because

1 times m-reduction [i] would yield (19, 55, 6858)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 5 311311 473010 464313 115059 638955 336775 599208 106125 598238 581697 339470 872683 774565 > 27⁵⁵ [i]
