Information on Result #585690
There is no linear OOA(2123, 127, F2, 5, 65) (dual of [(127, 5), 512, 66]-NRT-code), because 3 times depth reduction would yield linear OOA(2123, 127, F2, 2, 65) (dual of [(127, 2), 131, 66]-NRT-code), but
- 5 step m-reduction [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
Mode: Bound (linear).
