Information on Result #3150006
There is no digital (4, 22, 42)-net over F5, because 3 times m-reduction would yield digital (4, 19, 42)-net over F5, but
- extracting embedded orthogonal array [i] 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
- construction Y1 [i] would yield
Mode: Bound (linear).
