(128, 128+124, 2182)-Net in Base 4 — Upper bound on s
There is no (128, 252, 2183)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 52 899765 525124 872385 929806 723171 778977 443204 822079 956339 327977 446021 323154 537014 776829 811982 085614 870846 179230 036445 620064 103792 329061 488971 810053 799600 > 4252 [i]
