Information on Result #2157223
There is no linear OA(2171, 189, F2, 85) (dual of [189, 18, 86]-code), because 1 times truncation would yield linear OA(2170, 188, F2, 84) (dual of [188, 18, 85]-code), but
- residual code [i] would yield OA(286, 103, S2, 42), but
- the linear programming bound shows that M ≥ 158456 325028 528675 187087 900672 / 1705 > 286 [i]
Mode: Bound (linear).
