Information on Result #598653
There is no digital (67, 127, 161)-net over F2, because extracting embedded orthogonal array would yield linear OA(2127, 161, F2, 60) (dual of [161, 34, 61]-code), but
- construction Y1 [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]
- OA(234, 161, S2, 12), but
- discarding factors would yield OA(234, 154, S2, 12), but
- the Rao or (dual) Hamming bound shows that M ≥ 17486 314616 > 234 [i]
- discarding factors would yield OA(234, 154, S2, 12), but
- OA(2126, 149, S2, 60), but
Mode: Bound (linear).
