(185−119, 185, 265)-Net over F3 — Upper bound on s (digital)
There is no digital (66, 185, 266)-net over F3, because
- 2 times m-reduction [i] would yield digital (66, 183, 266)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3183, 266, F3, 117) (dual of [266, 83, 118]-code), but
- residual code [i] would yield OA(366, 148, S3, 39), but

There is no (66, 185, 289)-net in base 3, because
