(142−69, 142, 611)-Net in Base 3 — Upper bound on s

There is no (73, 142, 612)-net in base 3, because

1 times m-reduction [i] would yield (73, 141, 612)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 19 282118 421232 547755 601866 856883 216379 405067 016461 328059 904615 113849 > 3¹⁴¹ [i]
