(67−35, 67, 99539)-Net in Base 27 — Upper bound on s
There is no (32, 67, 99540)-net in base 27, because
- 1 times m-reduction [i] would yield (32, 66, 99540)-net in base 27, but
- the generalized Rao bound for nets shows that 27m ≥ 29517 532152 801614 091677 559816 839988 420554 520951 492558 570162 462747 782794 878973 432978 204565 577353 > 2766 [i]
