(125, 148, 5835234)-Net in Base 3 — Upper bound on s
There is no (125, 148, 5835235)-net in base 3, because
- 1 times m-reduction [i] would yield (125, 147, 5835235)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 13703 285002 586862 218993 911244 003486 293222 190498 305756 463071 874028 933531 > 3147 [i]
