Information on Result #562197
There is no linear OOA(522, 42, F5, 2, 18) (dual of [(42, 2), 62, 19]-NRT-code), because 3 step m-reduction would yield linear OA(519, 42, F5, 15) (dual of [42, 23, 16]-code), but
- construction Y1 [i] would yield
- linear OA(518, 23, F5, 15) (dual of [23, 5, 16]-code), but
- residual code [i] would yield OA(53, 7, S5, 3), but
- OA(523, 42, S5, 19), but
- discarding factors would yield OA(523, 41, S5, 19), but
- the linear programming bound shows that M ≥ 1431 381081 044673 919677 734375 / 117616 346784 > 523 [i]
- discarding factors would yield OA(523, 41, S5, 19), but
- linear OA(518, 23, F5, 15) (dual of [23, 5, 16]-code), but
Mode: Bound (linear).
