Information on Result #552039
There is no linear OOA(2145, 144, F2, 2, 78) (dual of [(144, 2), 143, 79]-NRT-code), because 10 step m-reduction would yield linear OA(2135, 144, F2, 68) (dual of [144, 9, 69]-code), but
- residual code [i] would yield linear OA(267, 75, F2, 34) (dual of [75, 8, 35]-code), but
- adding a parity check bit [i] would yield linear OA(268, 76, F2, 35) (dual of [76, 8, 36]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(268, 76, F2, 35) (dual of [76, 8, 36]-code), but
Mode: Bound (linear).
