(205−97, 205, 283)-Net in Base 2 — Upper bound on s
There is no (108, 205, 284)-net in base 2, because
- 1 times m-reduction [i] would yield (108, 204, 284)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2204, 284, S2, 96), but
- 15 times code embedding in larger space [i] would yield OA(2219, 299, S2, 96), but
- adding a parity check bit [i] would yield OA(2220, 300, S2, 97), but
- the linear programming bound shows that M ≥ 2 707506 179671 220537 436761 186277 555172 982275 381427 765331 317661 637213 928123 767152 572244 071765 637582 553088 / 1 434637 915544 533146 412054 075529 090625 > 2220 [i]
