(81−51, 81, 14881)-Net in Base 27 — Upper bound on s
There is no (30, 81, 14882)-net in base 27, because
- 1 times m-reduction [i] would yield (30, 80, 14882)-net in base 27, but
- the generalized Rao bound for nets shows that 27m ≥ 3 233484 735497 028392 008125 728104 852074 186472 230760 061934 355833 706123 353764 155472 519497 601040 169096 786721 684089 668357 > 2780 [i]
