(214, 259, 30665)-Net in Base 2 — Upper bound on s
There is no (214, 259, 30666)-net in base 2, because
- 1 times m-reduction [i] would yield (214, 258, 30666)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 463239 880052 785358 897855 192731 197540 017429 848368 745957 487907 493094 888127 372368 > 2258 [i]
