(25, 25+49, 8501)-Net in Base 27 — Upper bound on s

There is no (25, 74, 8502)-net in base 27, because

1 times m-reduction [i] would yield (25, 73, 8502)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 309 296554 799373 962119 248954 701556 812766 212460 764365 279409 036345 079097 374754 553074 332150 689930 523742 808433 > 27⁷³ [i]
