(189−86, 189, 287)-Net in Base 2 — Upper bound on s
There is no (103, 189, 288)-net in base 2, because
- extracting embedded orthogonal array [i] would yield OA(2189, 288, S2, 86), but
- 11 times code embedding in larger space [i] would yield OA(2200, 299, S2, 86), but
- adding a parity check bit [i] would yield OA(2201, 300, S2, 87), but
- the linear programming bound shows that M ≥ 6062 729839 358588 077129 287653 744482 312929 554681 473387 231550 995785 979703 893542 676711 534073 403563 590830 522368 / 1273 266655 863433 158102 727954 895995 795355 723661 > 2201 [i]
- adding a parity check bit [i] would yield OA(2201, 300, S2, 87), but
