(199−128, 199, 279)-Net over F3 — Upper bound on s (digital)
There is no digital (71, 199, 280)-net over F3, because
- 2 times m-reduction [i] would yield digital (71, 197, 280)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3197, 280, F3, 126) (dual of [280, 83, 127]-code), but
- residual code [i] would yield OA(371, 153, S3, 42), but
