Information on Result #564377
There is no linear OOA(2577, 148, F25, 2, 74) (dual of [(148, 2), 219, 75]-NRT-code), because 7 step m-reduction would yield linear OA(2570, 148, F25, 67) (dual of [148, 78, 68]-code), but
- construction Y1 [i] would yield
- OA(2569, 73, S25, 67), but
- the linear programming bound shows that M ≥ 24178 564222 846123 668546 399721 917528 895562 151649 914153 732205 158997 548011 257094 913162 291049 957275 390625 / 7242 > 2569 [i]
- linear OA(2578, 148, F25, 75) (dual of [148, 70, 76]-code), but
- discarding factors / shortening the dual code would yield linear OA(2578, 103, F25, 75) (dual of [103, 25, 76]-code), but
- residual code [i] would yield OA(253, 27, S25, 3), but
- discarding factors / shortening the dual code would yield linear OA(2578, 103, F25, 75) (dual of [103, 25, 76]-code), but
- OA(2569, 73, S25, 67), but
Mode: Bound (linear).
