Information on Result #132469
There is no OOA(2191, 180, S2, 2, 107), because 17 step m-reduction would yield OA(2174, 180, S2, 90), but
- adding a parity check bit [i] would yield OA(2175, 181, S2, 91), but
- the (dual) Plotkin bound shows that M ≥ 1 149371 655649 416643 768760 270362 731887 714054 341637 701632 / 23 > 2175 [i]
Mode: Bound.
