(162−69, 162, 295)-Net in Base 2 — Upper bound on s
There is no (93, 162, 296)-net in base 2, because
- 1 times m-reduction [i] would yield (93, 161, 296)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2161, 296, S2, 68), but
- 3 times code embedding in larger space [i] would yield OA(2164, 299, S2, 68), but
- adding a parity check bit [i] would yield OA(2165, 300, S2, 69), but
