Information on Result #553506
There is no linear OOA(2198, 252, F2, 2, 94) (dual of [(252, 2), 306, 95]-NRT-code), because 2 step m-reduction would yield linear OA(2196, 252, F2, 92) (dual of [252, 56, 93]-code), but
- construction Y1 [i] would yield
- linear OA(2195, 232, F2, 92) (dual of [232, 37, 93]-code), but
- construction Y1 [i] would yield
- linear OA(2194, 220, F2, 92) (dual of [220, 26, 93]-code), but
- adding a parity check bit [i] would yield linear OA(2195, 221, F2, 93) (dual of [221, 26, 94]-code), but
- OA(237, 232, S2, 12), but
- discarding factors would yield OA(237, 217, S2, 12), but
- the Rao or (dual) Hamming bound shows that M ≥ 139173 045698 > 237 [i]
- discarding factors would yield OA(237, 217, S2, 12), but
- linear OA(2194, 220, F2, 92) (dual of [220, 26, 93]-code), but
- construction Y1 [i] would yield
- OA(256, 252, S2, 20), but
- discarding factors would yield OA(256, 224, S2, 20), but
- the Rao or (dual) Hamming bound shows that M ≥ 74952 904195 135741 > 256 [i]
- discarding factors would yield OA(256, 224, S2, 20), but
- linear OA(2195, 232, F2, 92) (dual of [232, 37, 93]-code), but
Mode: Bound (linear).
