Information on Result #580029
There is no linear OOA(2188, 225, F2, 4, 91) (dual of [(225, 4), 712, 92]-NRT-code), because 2 times depth reduction would yield linear OOA(2188, 225, F2, 2, 91) (dual of [(225, 2), 262, 92]-NRT-code), but
- 5 step m-reduction [i] would yield linear OA(2183, 225, F2, 86) (dual of [225, 42, 87]-code), but
- construction Y1 [i] would yield
- linear OA(2182, 211, F2, 86) (dual of [211, 29, 87]-code), but
- adding a parity check bit [i] would yield linear OA(2183, 212, F2, 87) (dual of [212, 29, 88]-code), but
- OA(242, 225, S2, 14), but
- discarding factors would yield OA(242, 219, S2, 14), but
- the Rao or (dual) Hamming bound shows that M ≥ 4 498367 189624 > 242 [i]
- discarding factors would yield OA(242, 219, S2, 14), but
- linear OA(2182, 211, F2, 86) (dual of [211, 29, 87]-code), but
- construction Y1 [i] would yield
Mode: Bound (linear).
