Information on Result #3019159
There is no (31, 69, 72)-net in base 2, because 2 times m-reduction would yield (31, 67, 72)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(267, 72, S2, 36), but
- adding a parity check bit [i] would yield OA(268, 73, S2, 37), but
- the (dual) Plotkin bound shows that M ≥ 7083 549724 304467 820544 / 19 > 268 [i]
- adding a parity check bit [i] would yield OA(268, 73, S2, 37), but
Mode: Bound.
