(220−115, 220, 221)-Net in Base 2 — Upper bound on s
There is no (105, 220, 222)-net in base 2, because
- 11 times m-reduction [i] would yield (105, 209, 222)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2209, 222, S2, 104), but
- the linear programming bound shows that M ≥ 18 376994 896163 229078 786695 830800 490439 647194 147395 819913 877265 580032 / 16165 > 2209 [i]
- extracting embedded orthogonal array [i] would yield OA(2209, 222, S2, 104), but
