(215−99, 215, 290)-Net in Base 2 — Upper bound on s
There is no (116, 215, 291)-net in base 2, because
- 1 times m-reduction [i] would yield (116, 214, 291)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2214, 291, S2, 98), but
- 9 times code embedding in larger space [i] would yield OA(2223, 300, S2, 98), but
- the linear programming bound shows that M ≥ 1 797227 776840 883681 896516 291018 079602 556004 736527 384481 376471 307374 972535 986485 205069 933364 379648 / 112622 624143 760877 566730 935625 > 2223 [i]
- 9 times code embedding in larger space [i] would yield OA(2223, 300, S2, 98), but
