Information on Result #520176
There is no (21, 47, 51)-net in base 2, because extracting embedded orthogonal array would yield OA(247, 51, S2, 26), but
- adding a parity check bit [i] would yield OA(248, 52, S2, 27), but
- the (dual) Plotkin bound shows that M ≥ 2251 799813 685248 / 7 > 248 [i]
Mode: Bound.
