Information on Result #3152829
There is no digital (21, 149, 438)-net over F9, because 2 times m-reduction would yield digital (21, 147, 438)-net over F9, but
- extracting embedded orthogonal array [i] would yield linear OA(9147, 438, F9, 126) (dual of [438, 291, 127]-code), but
- residual code [i] would yield OA(921, 311, S9, 14), but
- the Rao or (dual) Hamming bound shows that M ≥ 109 707795 121304 339193 > 921 [i]
- residual code [i] would yield OA(921, 311, S9, 14), but
Mode: Bound (linear).
