(179−114, 179, 268)-Net over F3 — Upper bound on s (digital)
There is no digital (65, 179, 269)-net over F3, because
- extracting embedded orthogonal array [i] would yield linear OA(3179, 269, F3, 114) (dual of [269, 90, 115]-code), but
- residual code [i] would yield OA(365, 154, S3, 38), but

(179−114, 179, 287)-Net in Base 3 — Upper bound on s
There is no (65, 179, 288)-net in base 3, because
- 5 times m-reduction [i] would yield (65, 174, 288)-net in base 3, but
- extracting embedded orthogonal array [i] would yield OA(3174, 288, S3, 109), but
- 12 times code embedding in larger space [i] would yield OA(3186, 300, S3, 109), but
