(227−118, 227, 229)-Net in Base 2 — Upper bound on s
There is no (109, 227, 230)-net in base 2, because
- 10 times m-reduction [i] would yield (109, 217, 230)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2217, 230, S2, 108), but
- the linear programming bound shows that M ≥ 26 959946 667150 639794 667015 087019 630673 637144 422540 572481 103610 249216 / 93 > 2217 [i]
- extracting embedded orthogonal array [i] would yield OA(2217, 230, S2, 108), but
