(76, 216, 279)-Net over F3 — Upper bound on s (digital)
There is no digital (76, 216, 280)-net over F3, because
- 2 times m-reduction [i] would yield digital (76, 214, 280)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3214, 280, F3, 138) (dual of [280, 66, 139]-code), but
- residual code [i] would yield OA(376, 141, S3, 46), but

There is no (76, 216, 299)-net in base 3, because
