(175, 214, 885027)-Net in Base 3 — Upper bound on s
There is no (175, 214, 885028)-net in base 3, because
- 1 times m-reduction [i] would yield (175, 213, 885028)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 423478 128539 884887 639594 571161 713506 967200 977589 874994 207427 018331 172492 973107 164078 385085 182966 001713 > 3213 [i]
