(196−88, 196, 290)-Net in Base 2 — Upper bound on s
There is no (108, 196, 291)-net in base 2, because
- extracting embedded orthogonal array [i] would yield OA(2196, 291, S2, 88), but
- 8 times code embedding in larger space [i] would yield OA(2204, 299, S2, 88), but
- adding a parity check bit [i] would yield OA(2205, 300, S2, 89), but
- the linear programming bound shows that M ≥ 416927 463188 475542 795463 940731 898983 181308 104641 213119 598295 609827 594303 154474 074874 094714 331435 368448 / 5584 401256 756961 297780 513782 298869 514125 > 2205 [i]
