(129, 129+29, 14344)-Net in Base 2 — Upper bound on s
There is no (129, 158, 14345)-net in base 2, because
- 1 times m-reduction [i] would yield (129, 157, 14345)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 182842 226650 824949 069626 852439 940204 938017 121984 > 2157 [i]
