(163, 188, 259646)-Net in Base 2 — Upper bound on s
There is no (163, 188, 259647)-net in base 2, because
- 1 times m-reduction [i] would yield (163, 187, 259647)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 196 161591 018939 865742 599054 715181 182621 857529 096563 237293 > 2187 [i]
