Information on Result #598730
There is no digital (82, 156, 190)-net over F2, because extracting embedded orthogonal array would yield linear OA(2156, 190, F2, 74) (dual of [190, 34, 75]-code), but
- construction Y1 [i] would yield
- linear OA(2155, 178, F2, 74) (dual of [178, 23, 75]-code), but
- adding a parity check bit [i] would yield linear OA(2156, 179, F2, 75) (dual of [179, 23, 76]-code), but
- OA(234, 190, 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
- linear OA(2155, 178, F2, 74) (dual of [178, 23, 75]-code), but
Mode: Bound (linear).
