(221−104, 221, 251)-Net in Base 2 — Upper bound on s
There is no (117, 221, 252)-net in base 2, because
- extracting embedded orthogonal array [i] would yield OA(2221, 252, S2, 104), but
- the linear programming bound shows that M ≥ 43402 152983 641643 064849 413563 996676 473160 458830 220874 716324 448351 940769 742848 / 9596 684825 > 2221 [i]
