(236−115, 236, 258)-Net in Base 2 — Upper bound on s
There is no (121, 236, 259)-net in base 2, because
- 7 times m-reduction [i] would yield (121, 229, 259)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2229, 259, S2, 108), but
- the linear programming bound shows that M ≥ 17498 495097 789040 453213 386774 622994 352540 479460 641070 835741 390745 701581 780259 176448 / 19 797109 545047 > 2229 [i]
- extracting embedded orthogonal array [i] would yield OA(2229, 259, S2, 108), but
