Information on Result #596151
There is no linear OOA(2257, 278, F2, 7, 127) (dual of [(278, 7), 1689, 128]-NRT-code), because 5 times depth reduction would yield linear OOA(2257, 278, F2, 2, 127) (dual of [(278, 2), 299, 128]-NRT-code), but
- 3 step m-reduction [i] would yield linear OA(2254, 278, F2, 124) (dual of [278, 24, 125]-code), but
- residual code [i] would yield linear OA(2130, 153, F2, 62) (dual of [153, 23, 63]-code), but
- adding a parity check bit [i] would yield linear OA(2131, 154, F2, 63) (dual of [154, 23, 64]-code), but
- residual code [i] would yield linear OA(2130, 153, F2, 62) (dual of [153, 23, 63]-code), but
Mode: Bound (linear).
