(20, 53, 11727)-Net in Base 27 — Upper bound on s

There is no (20, 53, 11728)-net in base 27, because

1 times m-reduction [i] would yield (20, 52, 11728)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 269 987169 965686 338167 183083 684220 112542 887628 091333 937656 517619 404763 472897 > 27⁵² [i]
