(222−121, 222, 213)-Net in Base 2 — Upper bound on s
There is no (101, 222, 214)-net in base 2, because
- 21 times m-reduction [i] would yield (101, 201, 214)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2201, 214, S2, 100), but
- the linear programming bound shows that M ≥ 128760 731610 384372 798626 338535 112677 014899 081485 827624 307028 656128 / 29087 > 2201 [i]
- extracting embedded orthogonal array [i] would yield OA(2201, 214, S2, 100), but
