(182−117, 182, 252)-Net over F3 — Upper bound on s (digital)
There is no digital (65, 182, 253)-net over F3, because
- extracting embedded orthogonal array [i] would yield linear OA(3182, 253, F3, 117) (dual of [253, 71, 118]-code), but
- residual code [i] would yield OA(365, 135, S3, 39), but

(182−117, 182, 287)-Net in Base 3 — Upper bound on s
There is no (65, 182, 288)-net in base 3, because
- 8 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
