Information on Result #2172983
There is no linear OA(2551, 103, F25, 49) (dual of [103, 52, 50]-code), because 1 times truncation would yield linear OA(2550, 102, F25, 48) (dual of [102, 52, 49]-code), but
- construction Y1 [i] would yield
- linear OA(2549, 52, F25, 48) (dual of [52, 3, 49]-code), but
- linear OA(2552, 102, F25, 50) (dual of [102, 50, 51]-code), but
- discarding factors / shortening the dual code would yield linear OA(2552, 78, F25, 50) (dual of [78, 26, 51]-code), but
- residual code [i] would yield OA(252, 27, S25, 2), but
- bound for OAs with strength k = 2 [i]
- the Rao or (dual) Hamming bound shows that M ≥ 649 > 252 [i]
- residual code [i] would yield OA(252, 27, S25, 2), but
- discarding factors / shortening the dual code would yield linear OA(2552, 78, F25, 50) (dual of [78, 26, 51]-code), but
Mode: Bound (linear).
