(28, 28+63, 6817)-Net in Base 27 — Upper bound on s

There is no (28, 91, 6818)-net in base 27, because

1 times m-reduction [i] would yield (28, 90, 6818)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 667 479906 123264 739711 348567 602604 732605 625745 295404 769579 335042 490707 662856 495527 265801 946912 761520 006124 289167 185501 204073 419945 > 27⁹⁰ [i]
