(239−131, 239, 226)-Net in Base 2 — Upper bound on s
There is no (108, 239, 227)-net in base 2, because
- 25 times m-reduction [i] would yield (108, 214, 227)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2214, 227, S2, 106), but
- the linear programming bound shows that M ≥ 458 319093 341560 876509 339256 479333 721451 831455 183189 732178 761374 236672 / 17019 > 2214 [i]
- extracting embedded orthogonal array [i] would yield OA(2214, 227, S2, 106), but
