(254−138, 254, 244)-Net in Base 2 — Upper bound on s
There is no (116, 254, 245)-net in base 2, because
- 30 times m-reduction [i] would yield (116, 224, 245)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2224, 245, S2, 108), but
- the linear programming bound shows that M ≥ 227 481559 590216 982433 849553 220650 758912 788551 722735 940858 156798 416424 796160 / 8 133191 > 2224 [i]
- extracting embedded orthogonal array [i] would yield OA(2224, 245, S2, 108), but
