(241−27, 241, 2045874)-Net in Base 2 — Upper bound on s
There is no (214, 241, 2045875)-net in base 2, because
- 1 times m-reduction [i] would yield (214, 240, 2045875)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1 766852 748147 822965 353228 587766 114885 958155 410405 345511 544316 953959 397376 > 2240 [i]
