Information on Result #554819
There is no linear OOA(2247, 270, F2, 2, 121) (dual of [(270, 2), 293, 122]-NRT-code), because 1 step m-reduction would yield linear OA(2246, 270, F2, 120) (dual of [270, 24, 121]-code), but
- residual code [i] would yield OA(2126, 149, S2, 60), but
- the linear programming bound shows that M ≥ 40 354766 457887 934259 048521 444548 255732 989952 / 438495 > 2126 [i]
Mode: Bound (linear).
