(105, 105+25, 355935)-Net in Base 3 — Upper bound on s
There is no (105, 130, 355936)-net in base 3, because
- 1 times m-reduction [i] would yield (105, 129, 355936)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 35 371570 729312 355295 181848 038600 595988 626670 264591 962937 276673 > 3129 [i]
