(142−59, 142, 296)-Net in Base 2 — Upper bound on s
There is no (83, 142, 297)-net in base 2, because
- 1 times m-reduction [i] would yield (83, 141, 297)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2141, 297, S2, 58), but
- 2 times code embedding in larger space [i] would yield OA(2143, 299, S2, 58), but
- adding a parity check bit [i] would yield OA(2144, 300, S2, 59), but
