Information on Result #580705
There is no linear OOA(2247, 248, F2, 4, 129) (dual of [(248, 4), 745, 130]-NRT-code), because 2 times depth reduction would yield linear OOA(2247, 248, F2, 2, 129) (dual of [(248, 2), 249, 130]-NRT-code), but
- 9 step m-reduction [i] would yield linear OA(2238, 248, F2, 120) (dual of [248, 10, 121]-code), but
- residual code [i] would yield linear OA(2118, 127, F2, 60) (dual of [127, 9, 61]-code), but
- residual code [i] would yield linear OA(258, 66, F2, 30) (dual of [66, 8, 31]-code), but
- adding a parity check bit [i] would yield linear OA(259, 67, F2, 31) (dual of [67, 8, 32]-code), but
- “DHM†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(259, 67, F2, 31) (dual of [67, 8, 32]-code), but
- residual code [i] would yield linear OA(258, 66, F2, 30) (dual of [66, 8, 31]-code), but
- residual code [i] would yield linear OA(2118, 127, F2, 60) (dual of [127, 9, 61]-code), but
Mode: Bound (linear).
