(182−116, 182, 278)-Net over F3 — Upper bound on s (digital)
There is no digital (66, 182, 279)-net over F3, because
- 2 times m-reduction [i] would yield digital (66, 180, 279)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3180, 279, F3, 114) (dual of [279, 99, 115]-code), but
- residual code [i] would yield OA(366, 164, S3, 38), but

(182−116, 182, 288)-Net in Base 3 — Upper bound on s
There is no (66, 182, 289)-net in base 3, because
- 7 times m-reduction [i] would yield (66, 175, 289)-net in base 3, but
- extracting embedded orthogonal array [i] would yield OA(3175, 289, S3, 109), but
- 11 times code embedding in larger space [i] would yield OA(3186, 300, S3, 109), but
