Information on Result #586306
There is no linear OOA(2170, 180, F2, 5, 86) (dual of [(180, 5), 730, 87]-NRT-code), because 3 times depth reduction would yield linear OOA(2170, 180, F2, 2, 86) (dual of [(180, 2), 190, 87]-NRT-code), but
- 2 step m-reduction [i] would yield linear OA(2168, 180, F2, 84) (dual of [180, 12, 85]-code), but
- residual code [i] would yield linear OA(284, 95, F2, 42) (dual of [95, 11, 43]-code), but
- adding a parity check bit [i] would yield linear OA(285, 96, F2, 43) (dual of [96, 11, 44]-code), but
- “Bro†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(285, 96, F2, 43) (dual of [96, 11, 44]-code), but
- residual code [i] would yield linear OA(284, 95, F2, 42) (dual of [95, 11, 43]-code), but
Mode: Bound (linear).
