(149−63, 149, 295)-Net in Base 2 — Upper bound on s
There is no (86, 149, 296)-net in base 2, because
- 1 times m-reduction [i] would yield (86, 148, 296)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2148, 296, S2, 62), but
- 3 times code embedding in larger space [i] would yield OA(2151, 299, S2, 62), but
- adding a parity check bit [i] would yield OA(2152, 300, S2, 63), but
