Information on Result #552266
There is no linear OOA(2155, 159, F2, 2, 81) (dual of [(159, 2), 163, 82]-NRT-code), because 5 step m-reduction would yield linear OA(2150, 159, F2, 76) (dual of [159, 9, 77]-code), but
- residual code [i] would yield linear OA(274, 82, F2, 38) (dual of [82, 8, 39]-code), but
- adding a parity check bit [i] would yield linear OA(275, 83, F2, 39) (dual of [83, 8, 40]-code), but
- “DHM†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(275, 83, F2, 39) (dual of [83, 8, 40]-code), but
Mode: Bound (linear).
