(141, 141+19, 862862)-Net in Base 2 — Upper bound on s
There is no (141, 160, 862863)-net in base 2, because
- 1 times m-reduction [i] would yield (141, 159, 862863)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 730756 141671 314103 850077 317794 617992 017828 407256 > 2159 [i]
