(237−117, 237, 254)-Net in Base 2 — Upper bound on s
There is no (120, 237, 255)-net in base 2, because
- 9 times m-reduction [i] would yield (120, 228, 255)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2228, 255, S2, 108), but
- the linear programming bound shows that M ≥ 2 619796 018994 278921 458293 535821 563915 180233 403060 117761 392727 838179 034558 103552 / 5817 546149 > 2228 [i]
- extracting embedded orthogonal array [i] would yield OA(2228, 255, S2, 108), but
