(114, 114+29, 2575983)-Net in Base 4 — Upper bound on s
There is no (114, 143, 2575984)-net in base 4, because
- 1 times m-reduction [i] would yield (114, 142, 2575984)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 31 082778 062688 490074 771913 709923 053185 789015 180396 393105 136100 529909 580753 841992 960835 > 4142 [i]
