Information on Result #132471
There is no OOA(2191, 176, S2, 2, 109), because 21 step m-reduction would yield OA(2170, 176, S2, 88), but
- adding a parity check bit [i] would yield OA(2171, 177, S2, 89), but
- the (dual) Plotkin bound shows that M ≥ 47890 485652 059026 823698 344598 447161 988085 597568 237568 / 15 > 2171 [i]
