Information on Result #2157130
There is no linear OA(2163, 181, F2, 81) (dual of [181, 18, 82]-code), because 1 times truncation would yield linear OA(2162, 180, F2, 80) (dual of [180, 18, 81]-code), but
- residual code [i] would yield OA(282, 99, S2, 40), but
- the linear programming bound shows that M ≥ 9903 520314 283042 199192 993792 / 1885 > 282 [i]
Mode: Bound (linear).
