Information on Result #568273
There is no linear OOA(2258, 291, F2, 3, 126) (dual of [(291, 3), 615, 127]-NRT-code), because 2 times depth reduction would yield linear OA(2258, 291, F2, 126) (dual of [291, 33, 127]-code), but
- construction Y1 [i] would yield
- linear OA(2257, 281, F2, 126) (dual of [281, 24, 127]-code), but
- residual code [i] would yield linear OA(2131, 154, F2, 63) (dual of [154, 23, 64]-code), but
- OA(233, 291, S2, 10), but
- discarding factors would yield OA(233, 254, S2, 10), but
- the Rao or (dual) Hamming bound shows that M ≥ 8640 218941 > 233 [i]
- discarding factors would yield OA(233, 254, S2, 10), but
- linear OA(2257, 281, F2, 126) (dual of [281, 24, 127]-code), but
Mode: Bound (linear).
