(106, 106+21, 2326335)-Net in Base 3 — Upper bound on s
There is no (106, 127, 2326336)-net in base 3, because
- 1 times m-reduction [i] would yield (106, 126, 2326336)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 1 310023 460383 834269 490879 338630 119251 760653 516170 939419 213697 > 3126 [i]
