Information on Result #3031014
There is no (123, 255, 260)-net in base 2, because 2 times m-reduction would yield (123, 253, 260)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2253, 260, S2, 130), but
- adding a parity check bit [i] would yield OA(2254, 261, S2, 131), but
- the (dual) Plotkin bound shows that M ≥ 463168 356949 264781 694283 940034 751631 413079 938662 562256 157830 336031 652518 559744 / 11 > 2254 [i]
- adding a parity check bit [i] would yield OA(2254, 261, S2, 131), but
Mode: Bound.
