Information on Result #3150001
There is no digital (3, 17, 25)-net over F5, because 2 times m-reduction would yield digital (3, 15, 25)-net over F5, but
- extracting embedded orthogonal array [i] would yield linear OA(515, 25, F5, 12) (dual of [25, 10, 13]-code), but
- construction Y1 [i] would yield
- linear OA(514, 17, F5, 12) (dual of [17, 3, 13]-code), but
- linear OA(510, 25, F5, 8) (dual of [25, 15, 9]-code), but
- discarding factors / shortening the dual code would yield linear OA(510, 22, F5, 8) (dual of [22, 12, 9]-code), but
- construction Y1 [i] would yield
- linear OA(59, 12, F5, 8) (dual of [12, 3, 9]-code), but
- linear OA(512, 22, F5, 10) (dual of [22, 10, 11]-code), but
- discarding factors / shortening the dual code would yield linear OA(512, 18, F5, 10) (dual of [18, 6, 11]-code), but
- residual code [i] would yield OA(52, 7, S5, 2), but
- bound for OAs with strength k = 2 [i]
- the Rao or (dual) Hamming bound shows that M ≥ 29 > 52 [i]
- residual code [i] would yield OA(52, 7, S5, 2), but
- discarding factors / shortening the dual code would yield linear OA(512, 18, F5, 10) (dual of [18, 6, 11]-code), but
- construction Y1 [i] would yield
- discarding factors / shortening the dual code would yield linear OA(510, 22, F5, 8) (dual of [22, 12, 9]-code), but
- construction Y1 [i] would yield
Mode: Bound (linear).
