Information on Result #592509
There is no linear OOA(2151, 222, F2, 6, 70) (dual of [(222, 6), 1181, 71]-NRT-code), because 5 times depth reduction would yield linear OA(2151, 222, F2, 70) (dual of [222, 71, 71]-code), but
- construction Y1 [i] would yield
- linear OA(2150, 194, F2, 70) (dual of [194, 44, 71]-code), but
- construction Y1 [i] would yield
- linear OA(2149, 178, F2, 70) (dual of [178, 29, 71]-code), but
- adding a parity check bit [i] would yield linear OA(2150, 179, F2, 71) (dual of [179, 29, 72]-code), but
- OA(244, 194, S2, 16), but
- discarding factors would yield OA(244, 173, S2, 16), but
- the Rao or (dual) Hamming bound shows that M ≥ 17 734855 699135 > 244 [i]
- discarding factors would yield OA(244, 173, S2, 16), but
- linear OA(2149, 178, F2, 70) (dual of [178, 29, 71]-code), but
- construction Y1 [i] would yield
- OA(271, 222, S2, 28), but
- discarding factors would yield OA(271, 209, S2, 28), but
- the Rao or (dual) Hamming bound shows that M ≥ 2400 648072 841355 873622 > 271 [i]
- discarding factors would yield OA(271, 209, S2, 28), but
- linear OA(2150, 194, F2, 70) (dual of [194, 44, 71]-code), but
Mode: Bound (linear).
